摘要
概述了国内外有关金属间化合物/Al2O3,TiC陶瓷基复合材料的研究现状,特别是工艺、结构和性能间的关系以及增韧补强的机理,指出了存在的问题及今后的发展趋势.目前金属间化合物陶瓷基复合材料(I/CMC)大多是以高纯单质或化合物粉为原料,采用粉末冶金或原位合成等工艺来制备.而以天然钛铁矿为原料,原位合成制备金属间化合物/Al2O3-TiC陶瓷基复合材料是I/CMC发展的趋势之一.
The recent studies of Intermetallics/Al_ 2 O_ 3 and TiC ceramics based on the composites are introduced,especially the relations among techniques,structure and properties as well as the mechanism of strengthening and toughening.Some problems,the possible solutions and current development are also presented.Intermetallics/ceramics matrix composite (I/CMC) can be prepared through powder metallurgy or in-situ by pure element or compound.Intermetallics/Al_ 2 O_ 3 -TiC ceramics matrix composites by in-situ from ilmenite will be one of the present development.
