相变增韧 meaning in Chinese

transformation toughening

And even increaseed again a little . in this paper , the result of experiment has been discussed carefully useing transformation toughening and microcrack toughening mechanism
本文从zroz相变增韧和微裂纹增韧两种机制出发对实验结果进行了深入研究和讨论。
The principles have been successfully applied in those that zro2 stress inducement change phase and fiber , crystal beard or the second particles improve the toughness
上述两类增韧原理分别在zro _ 2应力诱导的相变增韧和纤维、晶须或二相粒子的补强增韧中得到以成功的应用。
The addition of y - zro2 improves the fracture toughness of pcd and the grinding ratio also increases with the y2o3 content increasing . the optimum comprehensive properties of pcd can be achieved as the y - zro2 powders contain 2mol % y2o3 . aluminum addition in si3n4 or si3n4 bond pcbn can prevent y - zro2 powders from forming the nontransformable tetragonal phase
在si _ 3n _ 4及si _ 3n _ 4中介结合的pcbn中加入适量的al作为烧结助剂，可以避免不可相变的t相zro _ 2形成，使应力诱导相变增韧高温高压烧结的氮化硅系陶瓷成为可能。
