陶瓷颗粒增强钛基复合材料的研究进展

The Progress in Research on Ceramic Particulate-Reinforced Titanium Matrix Composites

陶瓷颗粒增强钛基复合材料具有高比强度、低密度、高弹性模量等特点,成为钛基复合材料发展领域新的研究热点。系统地介绍了陶瓷颗粒增强钛基复合材料的最新研究进展和发展趋势,重点论述了该类复合材料组分的选择与改善匹配性的措施,并简要介绍了几种常用的制备方法,包括金属粉末注射成形法(MIM)和原位合成法(In-Situ)及其与传统制备方法结合形成的新工艺。

Ceramic particulate-reinforced titanium matrix composites have high specific strength, low density, high elastic modulus and other characteristics, so it becomes a new research area for the development of titanium matrix composites. The research advances and de- velopment trends for ceramic particle-reinforced titanium matrix composites in the latest were systematically described in the paper, where the focus of discussion was the components of such composite materials selection and improving the matching measures, and the several common preparation methods, including the metal powder injection molding （MIM） and in-situ synthesis （In-Situ） and its combination with traditional preparation methods were briefly introduced.
