摘要
相变温度对钛及钛合金加工和热处理来说具有重要意义。分别采用计算法和DSC差示扫描热量法分别得出Ti62421 s钛合金的相变温度为1006和1002℃左右。然后根据前两种方法得出的温度确定连续金相法的温度选择范围,用该方法测定出Ti62421 s钛合金的T(α+β)/β相变温度在995~1005℃区间内。将几种方法的测量结果进行比较,确定该合金的相变温度为1000℃。
The phase transformation temperature was very important to titanium and its alloys.The phase transformation temperature was obtained by calculation method and differential scanning calorimetry(DSC) with the value of 1006 and 1002 ℃,respectively.The temperature range of continuous metallographic method was chosen according to the temperature obtained,and T(α+β)/β phase transformation temperature was in the range of 995~1005 ℃.Compared the above methods,the phase transformation temperature was 1000 ℃.
