通过激光熔化沉积工艺制备出Ti60合金和TiCP(质量分数为5%)/Ti60复合材料薄壁材料，分析了两种材料的显微组织及600 ℃下的高温拉伸性能。结果表明，激光熔化沉积Ti60合金具有典型的魏氏组织特征，在亚晶界处和α/β界面处存在球形富钕稀土相；TiCP/Ti60复合材料中存在少量未完全熔化的TiC颗粒，熔化析出的TiC相呈断续链状，均匀分布于基体中，TiC与钛合金基体的界面结合良好。在600 ℃下，TiCP/Ti60复合材料的拉伸强度比Ti60合金提高了65 MPa，而延伸率明显降低。Ti60合金在高温下发生韧性断裂，而TiCP/Ti60复合材料的断口特征比较复杂，既有沿晶断裂和准解理断裂也有局部的韧性断裂。

Wall-like Ti60 alloy and TiCP(mass fraction 5%)/Ti60 titanium matrix composites are fabricated by laser direct deposition process. Their microstructure and tensile properties under 600 ℃ are investigated. The results indicate that the deposited Ti60 alloy presents a widmanstatten structure with some spherical rare earth phases distributing along the sub-grain boundaries and the α/β interface. For the deposited TiCP/Ti60 composites, there are some un-melted TiC particles and re-solidified TiC particles appear as discontinuous chain-like. The TiC particles distribute uniformly within the matrix with good interface bonding. Under 600 ℃, the ultimate tensile strength (UTS) of TiCP/Ti60 composites is 65 MPa higher than that of Ti60 alloy, following with decreased elongation. Ti60 alloy exhibit ductile fracture characteristics, while TiCP/Ti60 composite exhibit some complicated fracture characteristics including intergranular fracture, quasi-cleavage crack and local ductile rupture.
