Effect of TiC Addition and Cooling Rate on Mechanical Properties of 316L Stainless Steel Composites

Abstract:

The present research work concerns the development of TiC reinforced 316L stainless steel composites through powder metallurgical technology and sintered in vacuum. The effect of TiC particle addition and cooling rate on the mechanical properties of 316L stainless steel composites has been investigated. The results show that increasing the cooling rate caused enhancement of ultimate tensile strength and microhardness. However, the elongation to failure of the composites was decreased with the increase of cooling rate. The addition of TiC particle was found to improve the ultimate tensile strength of 316L stainless steel composites. The highest tensile strength was 648 MPa in specimens containing 5wt.% TiC. Further increase in TiC content to 10wt% results in a reduction in tensile strength to 631 MPa.
