Abstract
This fundamental manufacturing processes video program highlights heat treating's
versatility in altering the metallurgical properties of metals and alloys. This
versatility is broken down into three groups of processes: through-hardening
processes, surface hardening processes, and softening processes. The through-hardening
segment utilizes animations, phase diagrams and photomicrographs to explain
the hardening process and define its many variables. Quenching speed, mediums,
and temperature control are examined, as well as the tempering of heat treated
materials. The surface hardening section offers examples of the processes that
produce surface, or case hardened parts. Included are explanations of: flame
hardening, induction hardening, carburizing, nitriding, and carbonitriding.
The softening processes examined in this heat treating program include: annealing,
normalizing and stress relieving.
