摘要:

傳統鈦合金備受航空工業的青睞，而新型超高速、大運力航天器對鈦合金的比強度、比模量、耐熱性等性能提出了更高的要求。復合化是鈦合金實現高性能化的有效途徑之一。通過向輕質高強鈦合金基體中引入反應劑，生成異質增強相（微/納米顆粒和晶須），從而制備得到一種嶄新材料——原位自生鈦基復合材料（in�瞫itu TMCs），與鈦合金相比，該復合材料具有更高的強度和模量、優異的抗蠕變性能等，已成為航天領域一種不可替代的共性關鍵材料。近年來，TMCs的相關研究逐漸從制備工藝、均勻化控制、形變加工對組織性能的調控作用等轉為耐更高溫度TMCs的研制、復合構型的設計制備、近凈成形加工（如等溫鍛造、精密鑄造和增材制造等）以及構件應用的探索等。因此將圍繞航天用高性能TMCs的研制，綜述其在制備技術、形變加工工藝以及耐熱TMCs力學性能等方面的研究進展，總結in-situ TMCs未來的研究方向以及在各類航天器上的潛在應用方向。

Abstract:

Conventional titanium alloys are favored by aviation industry, while aiming at the development of new spacecrafts with higher-speed and larger-capacity, the performances of titanium alloys in terms of specific strength, specific modulus, heat resistance and other properties should be further improved. An effective way to improve the properties and performance of titanium alloys is to fabricate the titanium matrix composites (in-situ titanium matrix composites, in-situ TMCs). In these composites, heterogeneous reinforcements (micro/nano particles and whiskers) are formed by introducing reactants into the light-weight, high strength titanium alloy matrix, to possess higher strength and modulus and excellent creep resistance comparing with titanium alloys. Thus TMCs are expected to be prime candidate materials for the preparation of aerospace components. In recent years, the research interests of TMCs have gradually shifted from preparation technology, reinforcement-distribution homogenization, bulk deformation processing to the development of heat-resistant TMCs, the designed microstructural architectures, near-net-shaped forming (such as isothermal forging, precision-casting and additive manufacturing, etc.) and application test. In this study, the development of high-performance TMCs was focused, the research advances of fabrication methods, deformation processing and properties of heat-resistant TMCs were reviewed, and the potential research direction and application in various spacecraft were discussed.
