Experimental Investigation on Grinding Surface Condition of 9Mn2V under Different Tempering Processes

Abstract:

This paper investigates the surface condition of 9Mn2V in conventional surface grinding using SG abrasive under different tempering processes, which includes metallographic structure, micro-hardness, specific grinding energy, surface roughness, surface morphology and surface residual stress. The experimental results indicated that the specific grinding energy increased after the completion of tempering. The ground surface quality improved evidently with the times of tempering increasing. Meanwhile the ground surface was in a state of high tensile residual stress after quenching. After the second time of tempering, the residual stress had significantly been reduced.
