Weldability and Toughness Evaluation of Ceramic Reinforced Steel Matrix Composites (TiB2-RSMC)
This paper reports the production and weldability and toughness evaluation of TiB2 (ceramic particles) reinforced steel matrix composites. These ceramic particles are optimal reinforcements for steel matrix composites because of their high thermal stability at higher temperatures, high modulus of elasticity, good weldability, low density and relative stability within a steel matrix. This new composite family has received much attention as potential structural materials due to their high specific strength and stiffness. Thus, there is significant interest in developing iron and steel matrix composites and evaluating their dynamic behaviors due to their potential for use in the automotive industry. The goal of the research described in this paper is to study the usage of this new steel family in the manufacture of light structures. Therefore, titanium diboride TiB2 reinforced steel matrix composites were characterized by optical and scanning electron microscopy. The dynamic behaviours of the base metal and welded specimens were tested under impact crash test conditions.
