Paper Title:
Fabrication of TiC Particles Reinforced Hadfield Steel Matrix Composite and its Wear-Resistance
  Abstract

The TiC particles are selected as reinforced phase and the Hadfield steel as matrix. The powder metallurgy liquid phase sintering technique is adopted to fabricate TiC particles reinforced Hadfield steel matrix composites. The effects of elements Mo and Ni on the performance of the composites were studied. The impact wear tester is adopted to investigate the wear-resistant property of the composites under the different impact loads. Adding Mo can improve the interfacial bonding between the Hadfield steel and TiC, and the best adding ratio between Mo and TiC is 1:3.68. Adding 2%(vol.%)Ni can significantly improve the density and hardness of the composites. The experiment results of impact wear tests show that under the condition of low and middling loads, the composites display the best wear-resistant properties, moreover, the more TiC content is, the better wear-resistance property is. Under 2.0J impact energy, the wear resistance of the composite containing 40%(vol.%) TiC is 1.3 times of Hadfield steel.
