it is investigated the effect of vanadium and varying carbon content on Hadfield steel. The treatment also showed to have a direct influence on the wear resistance and hardness of manganese steel. According to the demands in upgrading the productivity and quality of products as well as to pursuit the optimum economy in wear industries; in the past decade the powder metallurgy approach has been replaced with the in situ ceramic–steel matrix composite. This is a synthesis technique to increase the life of the wear parts. The technique involves adding hard ceramic material in to molten steel as alloy elements and a more thermodynamically stable reinforcing phase will be formed during solidification. The process occurs by the nucleation and growth mechanism in the parent iron matrix that has a coherent interface with the iron matrix.
TiC carbide cermets and TiC-Fe/Fe bilayer composites consisting of a pure Fe layer and a TiC-Fe cermets layer were fabricated by hot-pressing sintering. The pure Fe layer contributes to the toughness of composites, and the TiC-Fe cermets layer endows the composites with an improved tensile strength and hardness. Steel-bonded titanium carbide (TiC) materials are manufactured by using advanced powder metallurgy technologies.
