| 摘 要： | 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。

| Abstract: | The thermo hydrogen treatment was performed on(TiB,TiC)/Ti-6Al-4V 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 ℃. |
