Effect of TiC/ZrC Addition on Microstructure and Properties of TiC-based Steel-bonded Cemented Carbide AITranslate
Abstract AITranslate
Composite TiC-ZrC steel bonded cemented carbide was manufactured by powder metallurgy techniques using TiC and ZrC as hard phases and other components such as Mo, Ni and C,and the effect of different TiC/ZrC mass ratio on the microstructure and properties of TiC-based steel-bonded cemented carbide was studied.The microstructure of the cemented carbide sample was analyzed by scanning electron microscope, and the hardness, bending strength and other mechanical properties of the samples were tested by Vickers hardness tester and universal electronic testing machine.The results show that when the TiC/ZrC mass ratio is 4/1,more shell phase of(Ti, Mo, Zr)C appears on TiC particles.As the mass ratio of TiC/ZrC decreases, the number of(Ti, Mo, Zr)C shell phase decreases.When the TiC/ZrC mass ratio is 4/1,the TiC particles in the cemented carbide are fine and uniformly distributed, and the mechanical pro-perties are the best with hardness and bending strength of 847.2 HV10 and 444.48 MPa, respectively.As the mass ratio of TiC/ZrC decreases, the ZrC grains in the cemented carbide gather together, resulting in the decrease of mechanical properties.
