介绍一种能快速显示NiCr40合金真实组织的机械抛光-电解浸蚀法。在显微镜下对该合金各种状态的组织进行了观察分析,并与同类进口材料的显微组织进行对比观察。
A mechanical polishing - electrolytic etching method that can quickly display the real structure of NiCr40 alloy is introduced. The microstructure of the alloy under various conditions was observed and analyzed, and compared with the same type of imported materials microstructure comparative observation.
