Materials science and engineering is a discipline that extends from the basic science of materials structure and properties to the design and evaluation of materials in engineering systems. Most engineers -- mechanical, civil, chemical, electrical -- work with materials on the job, and many become well acquainted with the properties of the materials they use most often. The role of a materials engineer is to understand why materials behave as they do under various conditions; to recognize the limits of performance that particular materials can attain; and to know what can be done during the manufacture of materials to meet the demands of a given application.

The Department of Materials Science and Engineering of the Case School of Engineering offers programs leading to the Bachelor of Science in Engineering, Master of Science, and Doctor of Philosophy degrees. The department conducts academic and research activities with metals, ceramics, composites, and electronic materials. Increasingly, the demands for new materials, and for improved materials in existing applications, transcend the traditional categories. The technological challenges that materials engineers face will continue to demand a breadth of knowledge across the spectrum of engineering materials.

Materials science draws on chemistry in its concern for bonding, synthesis, and composition of engineering materials and their chemical interactions with the environment. Physics provides a basis for understanding the mechanical, thermal, and electrical properties of materials, as well as the tools needed to ascertain the structure and properties of materials. Mathematics is used throughout materials manufacture and analysis. Ultimately, however, materials is an engineering discipline, bringing basic science tools to bear on the technological challenges related to materials products and their manufacture.

Electronic, Magnetic and Optical Materials

Electronic materials: silicon, germanium, gallium arsenide, silicon carbide; thin film dielectric, optical, and magnetic ceramics; synthesis and characterization of multicomponent ceramics, including barium titanate and materials for sensors, catalysts, and fuel cells.

FACILITIES

Materials Processing

The department's processing laboratories include facilities which permit materials processing from the liquid state (casting) as well as in the solid state (powder processing).

The department has its own foundry that houses mold making capabilities (green and bonded sand, permanent mold, and investment casting), induction melting furnaces of various capabilities for air melting of up to 1600 pounds, a dual chamber vacuum induction melting unit with a capacity of up to 30 pounds, a 100 ton squeeze casting press, and state-of-the-art testing and characterization equipment.

The Crystal Growth Laboratory has facilities for production of high purity electronic single crystals using a variety of furnaces with the additional capability of solidifying under large magnetic fields.

Secondary processing and working can be accomplished using a high-speed hot and cold rolling mill, swaging units, and a state-of-the art hydrostatic extrusion press. The department has heat treatment capabilities including numerous box, tube, and vacuum furnaces.

For the processing of powder metals or ceramics the department possesses a 300,000 pound press, a vacuum hot press (with capabilities of up to 7 ksi and 2300 C), a hot isostatic press (2000 C and 30 ksi), a 60 ksi wet base isostatic press, and glove boxes. Sintering can be performed in a variety of controlled atmospheres while a microcomputer-controlled precision dilatometer is available for sintering studies. Several ball mills, shaker mills, and a laboratory model attritor are also available for powder processing. In addition, facilities are available for sol-gel processing, glass melting, diamond machining; a spray dryer is available for powder granulation.

Mechanical Testing Facility

The Mechanical Testing Facility permits the determination of mechanical behavior of materials over loading rates ranging from static to impact, with the capability of testing under a variety of stress states under either monotonic or cyclic conditions. A variety of furnaces and environmental chambers are available to enable testing at temperatures ranging from -196 C to 1800 C. The facility is operated under the guidance of a full-time engineer.

The facility contains one of the few laboratories in the United States for high-pressure deformation and processing, enabling experimentation under a variety of stress states and temperatures. The equipment in this state-of-the-art facility includes:

The remainder of the equipment in the Mechanical Testing Facility is summarized below:

Environmental Stress Laboratories

These facilities include equipment for corrosion, oxidation, and adhesion and wear studies. A wide range of environments can be simulated and controlled: a) Aqueous corrosion: atmospheric, immersion and high pressure/high temperature in autoclaves and b) Oxidation: single and mixed gases over a range of temperatures and pressures. Special items include: electrochemical test equipment, environmental cracking test equipment, vacuum equipment for permeation studies, high sensitivity Cahn electrobalances for thermogravimetric studies and polymer/metal adhesion test fixtures.

Transmission Electron Microscope Laboratories

Three microscopes are available that provide virtually all transmission electron optical techniques needed for materials research and involve an installed capacity worth $2,000,000. The microscopes available are i) a JEOL 4000 EX 400 keV high resolution machine (point-to-point resolution of 0.19 nm) equipped with a GATAN TV camera (and requisite software for rigorous image interpretation); ii) a Philips CM20 200 keV analytical electron microscope equipped with a Tracor Northern high purity Ge energy dispersive spectroscopy (EDS) detector, a GATAN parallel electron energy loss spectrometer (PEELS) (the combination permitting microanalysis with ~10 nm spatial resolution for all elements between boron and uranium), and a GATAN image intensifier TV system; and iii) a JEOL 200CX 200 keV microscope, with point-to-point resolution of 0.35 nm, for general purpose microstructural analysis and for teaching.

Conventional TEM techniques, such as electron diffraction, bright- and dark-field imaging, and weak-beam dark-field (WBDF), are used routinely to analyze line defects (dislocations) and planar defects (for example, stacking faults) in materials. Specialized techniques, such as convergent beam electron diffraction (CBED) can be used to obtain crystallographic information and determine orientation relationships between different grains in polycrystalline materials, or between different phases in composite materials. The chemistry of microscopic regions (regions between dissimilar phases, or interfacial phases formed by reactions between the matrix and reinforcements) can be investigated using analytical TEM.

Specimen preparation facilities for transmission electron microscopy consist of dimplers, two ion-thinners with four ports, and two electropolishing units for TEM specimen thinning.

Scanning Electron Microscopy Laboratories

Scanning electron microscopy (SEM) and spectrochemical analysis provide valuable specimen investigation with great depth of field and realistic three-dimensional imaging at resolutions up to 100,000X. Determination of the topography of nearly any solid surface is possible. Spectrochemical studies are possible with the use of both wavelength and energy dispersive systems capable of detecting elements from boron to uranium. The department houses a Hitachi S-4500, a field emission electron microscope with two secondary electron detectors, a backscattered electron detector, and an infrared chamber scope. In addition, it has a Noran energy dispersive x-ray detection system and an EBSP detector capable of producing Kikuchi patterns suitable for crystallographic analysis. The microscope is capable of operating at a spatial resolution of less than 1.5 nm at 15 kV. It also performs well at reduced beam energies (1 kV), facilitating the observation of highly insulating materials.

Surface Science Laboratories

The Center for Surface Analysis of Materials (CSAM) enjoys state-of-the-art characterization of metal, alloy, ceramic, and polymer surfaces. These tools include a PHI 660 Scanning Auger Microprobe (SAM) for elemental analysis of surfaces and mapping, and PHI 3600 Secondary Ion Mass Spectrometry (SIMS), which provides surface sensitivities for species in the part per billion range. A PHI model 5400 instrument provides X-ray Photoelectron Spectroscopy (XPS or ESCA) capability, which produces information concerning chemical states. The latter two instruments are particularly useful for ceramic and polymer surfaces. With specimen heating, cooling, and depth profiling capabilities directly incorporated in these devices, subsurface regions and interfaces in composite structures, as well as at thin film substrate interfacial regions, can be examined and fully characterized.

The ion beam facility for the analysis of materials consists of a NEC 5SDH 1.7 MV tandem pelletron accelerator for the production of 3.4 MeV protons, 5.1 MeV alpha particles, and N ions with energies in excess of 7.0 MeV. Sample analysis takes place in a turbo-molecular pumped high vacuum chamber. The chamber is equipped with a computer-controlled 5 axis manipulator and has provisions for maintaining sample temperatures from 77 K to 1000 K. A Si surface barrier detector, NaI(Tl) scintillator, and a liquid nitrogen-cooled Si(Li) detector are used to detect scattered ions, characteristic gamma rays and characteristic X-rays, respectively.

This instrumentation can non-destructively provide composition and structure information in the near-surface region of materials using techniques such as Rutherford backscattering spectrometry (RBS), ion channeling, particle-induced X-ray analysis (PIXE), and nuclear reaction analysis (NRA). As with other analytic techniques, sensitivity, sampling depth, and depth resolution are sample dependent. However, sensitivities of 1 atomic percent, accuracies of 5%, and a depth resolution of 20 nm are usually easily achieved.

The typical specimen is a solid, vacuum-compatible material with lateral dimensions between 0.5 cm x 0.5 cm and 5 cm x 5 cm. However, PIXE and NRA can also be performed on non-vacuum compatible specimens such as liquids and irreplaceable artifacts of interest to museum curators and archeologists.

Electronic Properties Laboratory

The Electronic Characterization Laboratory is equipped for research studies and characterization of electrical properties of semiconductors and other electronic materials. The facility includes a deep level transient Spectroscopy System (DLTS) for the characterization of deep level impurities in semi-conductors, conductance and capacitance measurement techniques, a Hall effect system, and a scanning-tunneling microscope.

X-Ray Laboratory

The X-ray laboratory contains diffraction equipment for study of the structures of ceramics, metals, polymers, minerals, and single crystals of organic and inorganic compounds. A new Scintag diffractometer system includes a theta/theta wide angle goniometer, a 4.0 kW x-ray generator with copper tube, a third axis stress attachment, a thermoelectrically cooled Peltier germanium detector, a thin film analysis system, a dedicated PC for data acquisition, and a turbomolecular-pumped furnace attachment permitting sample temperatures up to 2000.

Computing

The department houses extensive computing equipment for research purposes and also maintains a computer lab expressly for student use, including IBM-compatible and Macintosh computers, laser printers, DECnet terminals, and a VAXstation 2000 with a large screen high resolution display.
