What a weird idea. I took two courses in metallurgy as part of my first engineering degree. I taught basics of metallurgy as part of manufacturing courses at two different schools. I'm betting I'm the only person here who has used a metalloscope (although Andrew might have), I'm sure I've done and observed more heat treating than most here, and I'm sure I've done and taught more physical testing of materials, including testing for modulus of elasticity, elastic limit, yield point, ultimate tensile strength, hardness by at least 3 or 4 different methods, etc.
Tell us about your education and experience in metallurgy, Tom. Especially, tell us where you were taught that plastically deformed metal can spontaneously return to its undeformed shape, and how that can happen. Nobody here believes you.
