Unformatted text preview: 9. Phase transformations for making steels: The concept of the TTT diagram, e.g., Why is there a “nose”? How are cooling rates controlled to produce coarse and fine pearlite/bainite and martensite? Applications of low, medium, and high-carbon steels and cast irons. (at least 2 of each) Alloyed steels, e.g., stainless steel 10 . Polymer materials : Structure : Describe the structure of a typical polymer ( e.g., polyethylene), Thermoplastic polymers vs. Thermoset polymers. What is a copolymer? Mechanical properties : Stress- strain behavior of a polymer and a plastic (contrast with stress-strain curves of ceramics and metals). Non-crystalline solids and glasses – distinction from crystalline solids. The notion of glass transition temperature and viscosity. Variation of Elastic/Relaxation modulus with temperature. Viscoelasticity and examples of a rubber/elastomer....
