Heat treatment can change the material properties in terms of its strength and resistance properties. The change in microstructure of the material when heat treated can influence the mechanical properties and the microstructure of the aluminium alloy. The aim is to study these effects to design products according toEFFECT OF HEAT-TREATMENT ON THE HARDNESS AND EFFECT OF HEAT-TREATMENT ON THE HARDNESS AND MECHANICAL PROPERTIES OF BORON ALLOYED STEEL M.
