通过高温显微镜,研究了Tc_4钛合金的饼材、棒材及粉末冶金材料、铸锭等试料高温下的组织,即再结晶、相变、晶界迁移等的组织变化;对比了Tc_4钛合金的高温组织与其炉冷组织,淬火组织的对应关系及异同点;进行了真空与充氩条件下的对比实验;讨论了高温下氧化膜的出现过程和消除办法;找到了用高温显微镜研究钛合金的较适宜的方法。
The microstructures of Tc_4 titanium alloy such as cakes, rods, powder metallurgy materials and ingots were studied by high temperature microscope at high temperature, ie the recrystallization, phase transformation and grain boundary migration. Tc_4 titanium alloy The corresponding relationship and the similarities and differences between the high temperature microstructure and the furnace cold tissue and the quenched microstructure; the contrast experiment under the condition of vacuum and argon filling; the appearance process and elimination method of the oxide film under high temperature were discussed; The more appropriate method.
