Check: this paper's printed header reads "Met-B6, Physical Metallurgy of Iron and Steel" and every question is ferrous physical metallurgy (equilibrium microstructures, thermomechanical treatment and austempering, CCT/TTT curve theory, martensite thermodynamics and crystallography, high-speed tool-steel heat treatment, cast-iron carbon morphology, and surface hardening) with no ceramics content anywhere.
