Check: this paper's printed header reads "10-Met-B6, Physical Metallurgy of Iron and Steel," and all seven questions are ferrous physical metallurgy (martensite crystallography and volumetric strain, cast-iron ductility, martensite tempering, TTT-curve theory, austempering of strapping steel, high-speed tool-steel heat treatment, and modern automotive sheet steels) with no ceramics content anywhere.
