Owing to the high strength and hardness, the mechanical polishing process usually can not remove the residual strain layer covered with the titanium-alloy specimen; the electropolishing process should be the ideal method for preparation of the Ti-alloy specimen for Electron Back Scatter Diffraction testing. 由于钛合金材料强度硬度较高,机械抛光通常不能去除试样表面的残余应变层,因而采用电解抛光是制备电子背散射衍射试样的理想方法。
The cellular metal is a type of structural material. In research of its mechanical properties, usually there are some difficulties existing in the experimental data, such as data scatter, non-apparentness of the regularity of results, and the confusion of concept. 多孔金属是一种结构型材料,在对其力学性能探讨的过程中,常存在实验数据离散性较大、结果规律性不明显以及概念相互混淆等问题。
