第二相弥散 meaning in English

second-phase dispersion

Many researches have showed that the mechanical properties of al2o3 - matrix ceramics in which ti ( c , n ) , tic or tin was dispersed could be improved a lot , which might be widely used in the field of machining . al2o3 - matrixed ceramics were fabricated by gas pressure sintering ( gps ) and gps with post - hip based on current techniques in this experiment . for al2o3 - ticn composite ceramics , the densitification process was controlled by the mechanism of solid phase sintering .
大量研究表明：采用ti ( c ， n ) 、 tic或tin作为第二相弥散颗粒所制备的氧化铝基复相陶瓷相对al _ 2o _ 3单相陶瓷而言，性能有了显著的提高这类复相陶瓷性能优良，在机械加工领域有着广泛的应用前景本实验采用气压烧结( gps )以及gps结合热等静压( hip )后处理两种工艺制备氧化铝基复相陶瓷。
