In the basic courses in the field of Materials Science and Engineering, the equilibrium structures in some metallic systems are treated as well as the main non-equilibrium structures, in especially steels.
The heat treatment procedures that normally are mentioned for steels are normalising, hardening by quenching and tempering, recrystallizing annealing, stress relieving and spheroidizing annealing (full annealing in the USA). For other metallic systems the particle hardening procedure by precipitation hardening of Al-Cu and other Al-alloys are treated.
The different hardening mechanisms, grain boundary-, solution-, particle- (particle and precipitation respectively) and strain- hardening are also normally treated in the basic courses.
Different hardening procedures often use a combination of hardening mechanisms and give an additive effect from them. Therefor it is possible to increase the mechanical strength of different alloy systems by combining these hardening mechanisms.
In practice the mechanical (as well as physical) properties of steels and other mechanical materials are achieved by a combination of thermal and mechanical treatments (thermo-mechanical treatments). This is enabled by the special possibilities that are created by the phase transformation that occurs at about 730 oC and in which it is possible to change the phase in the steel from the austenitic phase, with a FCC-lattice structure to one out of several possible structures that are in equilibrium or non-equilibrium state.
