Materials Engineering Technology (MAE T)

MAE T 201 Introduction to Materials Engineering Technology (3) An introduction to Materials Engineering Technology emphasizing relationships between structure and properties of engineering materials.

MAE T 201 Introduction to Materials Engineering Technology (3)

This course provides an overview of the basic science and technology of materials to two year associate degree students. The objective is to provide students with an understanding of how structure/property/processing relationships are developed and used for different types of materials with an emphasis on ferrous based metal alloys. Knowledge of these basics is needed to provide a foundation for study of the fundamentals and applications of powder metallurgy.

The course begins with a general introduction to materials science and materials engineering. Here the student is expected to gain an appreciation for the importance of studying materials. The first major topic covers the fundamental basis of the science of materials - atomic structure and bonding. Basic chemistry is reviewed, including the structure of atoms, chemical bonding, types of bonds, and the relationship of bonding to arrangement in the periodic table. The next topic addresses crystal structure and crystal geometry. Crystal structures for common metals are presented using the hard sphere model. The concepts of space lattice, unit cells, crystallographic directions, crystallographic planes, and polymorphism are discussed. Following crystal structures, the basic science of solidification is introduced and some common processing techniques used for fabricating metal components are presented. This includes direct pour ingot casting, semicontinuous casting, continuous casting, and growth of single crystals. Crystalline imperfections in solids and how these imperfections can influence material properties are discussed. The phenomenon of diffusion in solids is covered so that students may gain a quantitative understanding of the kinetics of rate processes and the effects of temperature on diffusion. A few practical industrial applications of diffusion processes are presented. An important topic covered in this course is interpretation of binary phase diagrams. The student is expected to understand the concepts of phase diagram, Gibb's phase rule, binary isomorphous alloy systems, lever rule, nonequilibrium solidification, binary eutectic alloy systems, binary peritectic alloy systems, and binary monotectic systems. In addition, invariant reactions and phase diagrams with intermediate phases and compounds are discussed. The last topic covers engineering alloys with emphasis on iron and steel alloys. Steel processing, alloy designation, phases, constituents, and invariant reactions in the iron-iron carbide phase diagram are reviewed. The student is introduced to
isothermal transformation diagrams and learns how to predict microstructures formed during common heat treatments. Alloy steels are presented, including classification of alloy steels, effects of alloying elements, and hardenability testing.
