This document provides a comprehensive answer key for the ME 6403 Engineering Materials and Metallurgy examination held in November/December 2017. The objective is to elucidate fundamental concepts related to materials science and metallurgy. The methodology includes the examination of phase diagrams, steel composition, and heat treatment processes. Key results indicate that austenite has a higher carbon solubility compared to ferrite due to its FCC structure, whereas ferritic stainless steels are generally magnetic. The role of boron in steel was highlighted as an enhancer of hardenability, while properties of PTFE and silicon carbide (SiC) were discussed in terms of their applications and mechanical characteristics. It was noted that brittle fracture occurs along specific crystallographic planes. The examination included tasks such as drawing the iron-iron carbide phase diagram and calculating the weight fraction of ferrite and cementite in eutectoid steel, illustrating the relationship between cooling rates, structure, and mechanical properties. Overall, the document serves as a crucial resource for understanding the principles underlying engineering materials and metallurgy.
