One Minute Mentor:Salt bath hardening line for high-speed steels

Tools that are heat treated in molten salt baths are heated up much more rapidly than by convection or radiation, thereby heat treating times are significantly shortened. The molten salt provides a ready source of heat and maintains the rate of heating necessary to reach equilibrium with the rate of heat absorption.

Metal reformation at nanometer scales

Massachusetts Institute of Technology has published a new study that shows what happens when crystalline grains in metals reform at nanometer scales, improving metal properties. This includes recrystallization, in which the metal is deformed and heated.
