【摘要】 制备了W-10Ti合金，研究了冷等静压（CIP）压力、热等静压（HIP）温度、高温处理对W-10Ti合金组织的影响。发现CIP能明显提高装料密度，有利于后续的HIP成形和元素扩散。提高CIP压力和HIP温度，能提高W与Ti扩散程度，HIP在1 300℃时，纯Ti相完全消除。高温处理温度为1 300、1 400、1 500、1 700℃时，富Ti相含量先降低再升高，在1 400℃时降至最低，为5.18%。在超过1 400℃处理时，富Ti相会发生共析转变。更多还原

【Abstract】 W-10Ti alloy was prepared,and the effects of cold isostatic pressing(CIP) pressure, hot isostatic pressing(HIP) temperature and high temperature treatment on the microstructure are studied. It is found that CIP can significantly increase the charge density,which is beneficial to HIP forming and element diffusion. The diffusion of W and Ti can be improved by increasing CIP pressure and HIP temperature. At HIP1 300 ℃, pure Ti phase is completely eliminated. When the high temperature treatment temperature is 1 300,1 400,1 500 and 1 700 ℃,the content of Ti-rich phase decreases first and then increases, and reaches the lowest at 1 400 ℃, which is 5. 18%.When treated at more than 1 400 ℃,the Ti-rich phase underwent eutectoid transformation.更多还原
