Progress in modern technology is often limited by the availability of suitable solid materials. The materials engineer must produce materials to meet the demands of the designers of jet engines and rocket boosters, microelectronic devices, optical components, medical prostheses, and many other products.
The principles that govern the processing and structure of materials to produce optimum mechanical and physical properties and performance are embodied in the materials engineering curriculum. The program is designed to produce engineers and scientists whose degrees represent useful specialization coupled with a broad background in all classes of materials.
Undergraduate students wishing to extend their education can undertake specialized study in a range of fields. These include research in ceramics, polymers, composites, nanostructured materials, high-temperature alloys, solidification, corrosion, deformation processing, welding, high-strength high-modulus materials, biomaterials, electronic materials, surface and molecular kinetics, glass science, and the origin of mechanical and physical properties in many different types of materials. Graduate students, in addition to pursuing classroom courses, conduct research in a variety of areas described below and write their theses based on this research. Extensive laboratories containing modern and sophisticated equipment are available.
For the student who likes to innovate and who wants to apply knowledge to the real problems of a modern technological society, materials science and engineering provides a broad range of exciting opportunities.
Research and Innovation Initiatives
Major research programs include fundamental studies of the solidification process and the effect of solidification under reduced gravity on the formation of dendritic structures, and practically oriented programs in the extrusion processing of aluminum alloys. In the latter program, studies of the complex interactions among stress, strain rate, and temperature during forming processes have made it possible to apply advanced software models to the control of metalworking operations. Studies of powder processing have made possible the extrusion processing of composite materials, while research on joining processes has led to synergistic coupling of adhesive bonding and spot welding technology in automotive sheet metal fabrication. New efforts focused on the synthesis, processing, and properties of nanostructured materials are expanding the capabilities of materials engineering and nanotechnology into additional areas including ceramics, metals, polymers, composites, and biomaterials. Novel applications of carbon nanotubes for device and chemical applications are under investigation, along with chemical, electrical, and mechanical isolation engineering using nanocomposites.
Materials for Microelectronic Systems
This research concentrates on materials problems associated with the interconnections between integrated circuit elements. Included are the growth of thin films of metals and both polymer and ceramic dielectric materials, the patterning and etching processes necessary for the fabrication of multilayer devices, and the planarization processes necessary for successful device fabrication.
Glasses and Ceramics
Research efforts focus on factors influencing the useful lifetime of glass components and the effect of environments, especially aqueous environments, on glass failure. In addition to the conventional applications such as windows and bottles, glasses are used as optical components such as optical communication fibers. Specifically, variation of the glass surface structure with time and its influence on glass properties are under investigation. Another emphasis is the development of nonoxide glasses, primarily those based on fluorides, as the transmitting medium in optical fibers for communications purposes.
High-Performance Composite Materials
These materials are used in industrial and consumer products due to their exceptional stiffness and strength-to-weight ratios. Applications of composites in the construction industry, such as steel bridge repairs using graphite-epoxy composites, are growing rapidly. Meanwhile, next generation conceptual plans for hybrid electric vehicles are using ceramic composite components for gas turbine engines and thermal recuperators. Composites research activities at Rensselaer include ceramic, metallic, and polymer matrix composites; micromechanics and modeling of both fabrication processes and materials properties; design with new materials; synthesis of new matrix materials; and all aspects of the fabrication and characterization of composites and composite structures. Of special note is the sailplane program, in which students have designed, fabricated, and tested an all-composite glider, which has now been flying for over seven years. A new project, the composite hybrid electric vehicle, has also been initiated and offers numerous opportunities for both graduate and undergraduate participation.

Objectives of the Undergraduate Curriculum
While certain objectives of an undergraduate education in engineering are common to all programs, there are subtle but important differences that require some subset of objectives specific to ensuring that all graduates have specialized technical knowledge in their chosen field.
In this regard, the graduates of the Department of Materials Science and Engineering’s baccalaureate program will be prepared for entry-level positions as Materials Engineers or for Graduate School. In particular, graduates will:
- Be able to use their broad knowledge of all classes of materials, and their background in mathematics and science, to contribute effectively to the solution of engineering problems, including problems involving design.
- Be especially aware of the interdependence of the structure, properties, processing, and performance of materials.
- Be broadly educated and thus capable of dealing with engineering problems and their societal consequences.
- Be experienced in working with multi-disciplinary teams and in communicating clearly and convincingly in a variety of contexts.
- Recognize the need for continued future learning and have a desire to engage in such learning.
The Department of Materials Science and Engineering offers programs leading to the M.S., M.Eng., and Ph.D. degrees.
Both the M.S. and M.Eng. degrees require completion of a minimum of 30 credit hours.
The Ph.D. degree requires completion of 90 credit hours. Students must complete at least 27 credits of course work, the remainder being credits for research work leading to a Ph.D. thesis. The program must include 18 credits from the five core graduate courses (Advanced Mechanical Properties (4 credits), Advanced Thermodynamics (4 credits), Advanced Structure of Materials (4 credits), Advanced Electronic Properties (3 credits), and Advanced Kinetics of Materials Reactions (3 credits). The first two courses are offered each Fall semester, and the latter three courses each Spring semester. The program must also include at least nine additional credits from three graduate level (6000-level) courses in the School of Engineering or the School of Science. The student must pass an oral preliminary examination covering the five core subjects, an oral candidacy examination, as well as the final examination on the Ph.D. thesis.
Courses directly related to the Materials Engineering curricula are described in the Course Descriptions section of this catalog primarily under the department code MTLE.
