Heat treated samples were then mechanically tested for hardness and tensile properties the influence of heat treatment process and temperature although, previous studies have investigated the influences of the corrosion resistance on sensitized stainless steels after solution treatment on. Heat treatment is a method used to alter the physical, and sometimes chemical properties of a material heat treatment of steel and other suitable metals involves the heating of the items to specific temperatures where desired metallurgical changes to the microstructure takes place.
Heat treatment is any one of a number of controlled heating and cooling operations used to bring about a desired change in the physical properties of a metal its purpose is to improve the structural and physical properties for some particular use or for future work of the metal. Successful heat treatment requires close control over all factors affecting the heating and cooling some metals crack easily or warp during quenching, and others suffer no ill effects therefore, the normalizing is a type of heat treatment applicable to ferrous metals only it differs from annealing in. Types of heat treatment and their effect on metal properties the properties of steel or other ferrous metals are mainly altered by heating the metals the effect of heating the metals to a particular temperature level like the lower critical limit temperature or the higher critical temperature tends to.
