| 摘 要： | 采用ANSYS有限元分析软件对BT22钛合金固溶热处理后降温阶段温度场进行模拟,并绘制热处理工件在降温过程中的温度分布等值图,从温度-时间曲线和工件内部不同部位温度曲线两个角度分析温降的不均匀性。通过对比实测曲线和模拟曲线发现两者的相对误差在2%～5%,同时把实测降温曲线分为3个阶段:快速降温阶段、平缓降温阶段和慢降温阶段,并分析其形成的原因。

| Abstract: | Internal temperature field of solid-solution treated BT22 titanium alloy during cooling was simulated using ANSYS finite element software and the temperature isopleth map of workpieces was plotted during this procedure.Inhomogeneity of temperature distribution during cooling was analyzed from two points of view,i.e.the temperature-time curve and position-temperature curve of workpiece interior.By comparison the relative error of actual curve and simulation curve is 2%-5%.The actual cooling curve was divided... |
