1 Clinical nurse specialist (CNS) â Working in hospitals, clinics, nursing homes, private offices, and community-based settings, CNSs handle a wide range of physical and mental health problems. 2  They also work in consultation, research, education, and administration.
I pass this heat treatment definition along until I'm corrected or find a more succinct, better one. Heat treatment is the controlled heating and cooling of a metal in order to change its properties. Forging is controlled heating and cooling but is not considered a heat treatment by metallurgists, probably because of the plastic deformation involved.
Extreme variations in size of metal parts complicate the work of the heat. treater and should be avoided in the designing of metal parts. This means. there is a limit to the overall size of parts that can be subjected to such. thermal processing. (Figure2.24) shows the conventional hardening, tempering process.
