- 摘要:
- 钛基复合材料具有轻质高强的突出特点，在航空航天等关键领域应用前景巨大。 经过近 40 年的研究，钛基复合材料领域的研究热点由最初的连续纤维增强为主发展到目前以非均匀颗粒/晶须增强为主， 但相关研究重点始终围绕着钛基复合材料的塑韧性提升这一目标。 其中有效的方法之一是对钛基复合材料进行微观结构设计，以实现其强韧性的良好匹配。 本文综述了钛基复合材料的几种主要的微观组织构型、相应的制备方法、力学性能以及存在的问题，对钛基复合材料的微观结构设计思路与实现方法进行了简要总结。With the prominent advantages of light and high strength, the titanium matrix composites (TMCs) processes a great application potential in the key areas, such as the aerospace field. After about 40 years of researches, the research focus has been developed from continuous long fibers reinforced TMCs into discontinuous reinforced titanium matrix composites (DRTMCs). However, these works always centered on improving the ductility and toughness of TMCs. One of effective method is microstructure design, which can achieve the good combination between strength, ductility and toughness of TMCs. This paper focuses on the reviews for the microstructure configurations, the corresponding preparation methods, mechanical properties and the inadequate of TMCs, having summarized the thoughts and implementation methods of microstructure design.
