采用粉末冶金法铺备TZM合金,通过SEM和EDS检测手段观察其显微组织,并在此基础上分析TZM合金的三种强化,即固溶强化、第二相强化和形变强化的强化机理。
TZM alloys were prepared by powder metallurgy,and their microstructure were observed by SEM and EDS. Based on the analysis results,the three strengthening mechanisms of TZM alloys are analysed, such as solid solution strengthening ,dispersion strengthening and deformation strengthening
