Class Information
Number: 148/903
Name: Metal treatment > Having portions of differing metallurgical properties or characteristics > Directly treated with high energy electromagnetic waves or particles (e.g., laser, electron beam)
Description: Art collection for stock material which has been treated with high energy electromagnetic waves or particles. This usually causes the surface of the stock to be suddenly heated, the mass of the stock then quickly cools the surface giving the effect of a quench resulting in a hardened surface.
