21-Mat-B7 Structure and Properties of Polymers: December 2016

Paper format. National Exams, December 2016 — 10-Met-B7, Physical Metallurgy of Non-Ferrous Metals and Alloys. Three hours, closed book, approved Casio/Sharp calculator only. Eight questions of 20 marks each; the rubric states that any five questions constitute a complete paper (100 marks total) and that only the first five appearing in the answer book are marked. All eight are answered here, because this set is a study resource rather than an exam script. The rubric explicitly notes that most questions require an essay-format answer and that clarity and organization are marked, so the answers below are written as structured prose rather than as note form.

Reference texts. The answers below are keyed to the works normally recommended for this syllabus code:

• J. R. Davis (ed.), ASM Specialty Handbook: Aluminum and Aluminum Alloys, ASM International — wrought/cast alloy designation systems, temper nomenclature, precipitation hardening.
• ASM Handbook, Vol. 2 — Properties and Selection: Nonferrous Alloys and Special-Purpose Materials, ASM International — magnesium, copper (brass/bronze), nickel/cobalt superalloy, and refractory/precious-metal sections.
• W. D. Callister and D. G. Rethwisch, Materials Science and Engineering: An Introduction, 10th ed. — recrystallization and grain growth (Ch. 7–8), phase diagrams, precipitation and intermetallic compounds (Ch. 9–11).
• M. J. Donachie, Titanium: A Technical Guide, 2nd ed., ASM International — alpha/beta/neutral stabilizers, aluminum-equivalent embrittlement.
• ASM Specialty Handbook: Nickel, Cobalt, and Their Alloys, ASM International — γ′ and carbide strengthening mechanisms, hot corrosion.
• R. E. Reed-Hill and R. Abbaschian, Physical Metallurgy Principles — intermetallic compounds, order-disorder transformations, refractory metal behaviour.
