Abstract

In this paper, we added different content of TiC and TiB2 particles powder into TiAl based alloy as particle reinforcement, and prepared different components of TiAl based composite. We also studied the influence of the content of TiC and TiB2 particles on the physical and mechanical properties of TiAl based composite. The results show that in a certain range, the physical properties of TiAl based alloy increase with the increase of TiC and TiB2 particle content, and the mechanical properties first increase and then decrease with the increase of TiC and TiB2 particle content. It is proved that the physical and mechanical properties of TiAl alloy can be effectively improved by adding the proper amount of TiC and TiB2 particles.
