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.
There are 3 broad classification in hardening process 1. physical hardening(surface/through hardening) 2. Thermochemical hardening 3. Thermomechanical hardening Physical hardening consists of simply heating the metal and queching them. Thermomechanical hardening consists of heating in the presence of a chemical and subsequently cooling it. Finally thermomechanical hardening consists of forming the metal at high temperatures and subsequently cooling it. This is just the tip of the ice berg.
