OPTIMIZATION OF HEAT TREATMENT PROCESS FOR 16MnCr5

摘要

The requirement of mechanical properties of the material depends on the application of the material. As the alloying elements have tendency to change the mechanical properties of the material, but an alternative can also be used to change the mechanical properties by heat treatment process after keeping a fixed alloying element and this will serve great reduction of cost paying for alloying element. By experiment it is found that heat treatment process on the alloy steel can change the mechanical properties of the material without the variation of alloying element in iron. As heat treatment is the variation of temperature and time, this variation can set optimum values of mechanical properties, so it becomes necessary to select a suitable heat treatment out of available number of processes so that desired mechanical properties can be maintained for required application. In this paper a comparative statement has been made for obtaining maximum yield strength and hardness for a highly stressed environment parts and optimum value has been selected for 16MnCr5 material with number of heat treatment processes. Consequently it is found that austempering; a heat treatment process gives the maximum value of hardness, UTS and yield strength with other excellent mechanical properties.
