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.
Heat Treatment Processes Hardening. Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used.
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.
