揭示了Ti-5Al-5Mo-5V-1Fe-1Cr合金在等温压缩过程中出现的组织不均匀现象。首先使用真空自耗炉制备出合金铸锭,而后进行热加工和热处理,使用热处理后的材料车削成圆柱形试样进行等温压缩试验,试样端面没有进行打磨、抛光处理,结果出现了严重的组织不均匀,在试样内部发现了轴对称分布的局部大变形区,这将增加材料受力时起裂的几率。并就该组织现象展开了研究。
The microstructure evolution of Ti-5Al-5Mo-5V-1Fe-1Cr alloy during isothermal compression was revealed. First, the use of vacuum consumable furnace prepared alloy ingot, and then hot and heat treatment, the use of heat treatment of the material into a cylindrical specimen isothermal compression test, the specimen end is not polished, polished, resulting in serious Inhomogeneous organization, the local large deformation zone with axisymmetric distribution was found in the specimen, which will increase the probability of initiation of cracking when the material is under stress. And conducted a study on the phenomenon of the organization.
