【摘要】 系统研究了AlON TiN复相材料力学性能和显微结构的关系。研究表明 ,随着TiN含量的增加 ,由于其对基体的弥散强化作用 ,使AlON TiN复相材料的力学性能提高 ;随着温度的提高 ,基体密实 ,复相材料的力学性能增加 ,温度过高 ,出现晶粒异常长大 ,从而又降低其力学性能。更多还原

【Abstract】 The relationship between mechanical property and microstructure in AlON-TiN composites was studied systematically. The results show that the strength increases with the increasing content of TiN because of the dispersed TiN grain. The strength of the composites increases, then decreases with the increasing sinter temperature because of grain enlargement.更多还原
