Effects of Ti on Microstructure and Properties of Wear-Resistant and Heat-Resistant Steel

According to the working condition of the wear-resistant and heat-resistant parts, it designed the composition of the wear-resistant and heat-resistant steel. Different amount of Ti were added to wear-resistant and heat-resistant steel. The effects of Ti on microstructure, hardness and wear resistance of wear-resistant and heat-resistant steel were researched by microstructure observation, x-ray diffraction，hardness and wear resistance test. The results show that proper amount Ti combines with C to form a certain number particle TiC in the wear-resistant and heat-resistant steel. TiC is dispersively distributed in austenite matrix and improves the hardness and wear resistance of wear-resistant and heat-resistant steel greatly. It has a certain economic benefit.
