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.
