金属间化合物作为结构材料近几年倍受众多研究者重视 ,但作为第二相物质与结构陶瓷形成复合材料的研究却相对较少。本文是一篇关于金属间化合物增韧陶瓷的综述文章 ,对重要的金属间化合物如Ni3Al,MoSi2 等的性能特点 ,用其增韧Al2 O3,Si3N4等陶瓷材料的效果、机理作了重点分析、评述。 Many researchers have paid much attention to the intermetallic compounds as the structural material, but relatively few studies on the composite materials for the second phase material and the structural ceramics have shown. This article is a review article on the toughening of intermetallic ceramics. The important properties of intermetallic compounds, such as Ni3Al and MoSi2, are analyzed with emphasis on the effects and mechanisms of toughening Al2 O3, Si3N4 and other ceramic materials. Comment.
