Weldability and toughness evaluation of the ceramic reinforced steel matrix composites (TIB2-RSMC)

Abstract

The general idea of this paper is to produce TiB2 (ceramic particles) reinforced steel matrix composites. These ceramic particles are the best reinforcements for steel matrix composites because of their high thermal stability at higher temperature, high modulus of elasticity, good wetability, low density and their relative stability with steel matrix. This type of new composite family has received much attention as potential structural materials for their high specific strength and stiffness. Therefore, there is a significant interest in developing iron and steel matrix composites and evaluating dynamic behaviours due to their potential usage in automotive industry in future. Final purpose of this paper is to use of the steel sheet for the manufacturing of the lighted structure and manufacturing processes of this sheet. Titanium carbide and titanium diboride TiB2 reinforced steel matrix composites was therefore characterised by optical and scanning electron microscopy. Dynamic behaviours of the base metal and welded specimens have been tested to simulate under the impact-crash test conditions. ©2010 Society for Experimental Mechanics Inc.
