Abstract:
Heat treatment of different materials has been constantly altered throughout centuries from blacksmith’s art to high tech science technology nowadays. With the evolution of techniques and improvement of chemical composition of metals, an increasing interest evoked in development of heat treatment techniques and with it influence on the properties of selected material. Heat-treating processes can involve the heating or cooling of selected material by cryogenic treatment.
