对原位反应制备的（TiB，TiC）／Ti-6Al-4V复合材料进行热氢处理，研究了不同状态下复合材料的显微组织和力学性能。结果表明：置氢处理降低了复合材料的相变温度，提高了β相的含量；氢含量为0和0．15％的复合材料热锻后获得α和β相，氢含量为0．6％的复合材料获得α″马氏体和β相；除氢处理提高了复合材料在室温和400℃下的屈服强度和抗拉强度。
The thermo hydrogen treatment was performed on （TiB, TiC）/Ti-6AL4V composites prepared in situ reaction, and the microstructure and mechanical properties of the composite in different states were studied. The results show that hydrogenation decreased the phase transformation temperature and increased the β phase content, α and β phases were obtained in the composite with 0 and 0. 15wt% H after hot-forging, while α″ martensite and β phase was obtained in the composite with 0. 6wt% H. Dehydrogenation treatment increased the yield strength and tensile strength of the composite at room temperature and at 400 ℃.
