Paper format. National Exams, May 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.
Nothing on this paper is a polymer question; the syllabus actually examined is the physical metallurgy, strengthening and heat treatment of non-ferrous engineering alloys — aluminum, magnesium, copper-base alloys (brasses and bronzes), nickel- and cobalt-base superalloys, and titanium.
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 and stress-corrosion cracking of high-strength Al alloys.
- ASM Handbook, Vol. 2 — Properties and Selection: Nonferrous Alloys and Special-Purpose Materials, ASM International — magnesium, copper (brass/bronze), and nickel/cobalt superalloy 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 and precipitation (Ch. 9–11), corrosion (Ch. 17).
- M. J. Donachie, Titanium: A Technical Guide, 2nd ed., ASM International — alpha/beta/neutral stabilizers, aluminum-equivalent embrittlement, transformed-vs-equiaxed microstructure toughness.
- ASM Specialty Handbook: Nickel, Cobalt, and Their Alloys, ASM International — γ′ and carbide strengthening mechanisms, hot corrosion.
