| Abstract: | The composite reinforced by in-situ -TiB2 was prepared by vacuum sintering of boron （B）, titanium （Ti） and copper （Cu） powders, which were evenly mixed and then cold molding by press machine. The reinforced particles were analyzed by Thermal Analysis and XRD. The microstructures composites were observed with SEM. And the mechanical properties of composites were tested. The results showed that the reinforced phase of TiB2 in Ti-B-Cu was formed by the reaction of in-situ. The size of TiB2 increases with increasing the content of B and Ti powders. The TiB2/Cu composite fabricated by this technique has excellent mechanical properties. The highest hardness is 610. 7 MPa. |
