摘要
通过Ti和Al制备的Ti-Al系金属间化合物及复合材料由于具有优异的物理、化学和力学性能,在航空航天、汽车以及其它领域具有良好的应用前景.这些材料包括TiAl3.γ-TiAl 和α2-Ti3Al等金属间化合物,以及Ti/Al、Ti/α2-Ti3Al、Ti/γ-TiAl、Ti/TiAl3、Ti/TiAl3/Al和Al/TiAl3等金属-金属或金属-金属间化合物复合材料.在上述材料的制备过程中,会涉及到各种Ti-Al反应扩散过程.因此,对Ti-Al反应扩散机理及动力学的深入理解,有助于合理高效地制备Ti-Al系金属间化合物及复合材料.目前对Ti-Al反应扩散机理及动力学的研究非常广泛,但很多结论仍存在争议.本文(下)部分系统综述了 Ti-Al反应扩散动力学的研究现状,并对其未来的研究方向进行了展望.
Abstract
The Ti-Al system intermetallic compounds and composites fabricated from Ti and Al,such as TiAl3,α-TiAl and α2-Ti3Al intermetallic compounds,and Ti/Al,Ti/α2-Ti3Al,Ti/γ-TiAl,Ti/TiAl3,Ti/TiAl3/Al and Al/TiAl3 metal-metal and metal-intermetallic compound composites,have good application prospects in aerospace,automotive and other fields owing to their excellent physical,chemical and mechanical properties.The preparation of the above materials involves a variety of Ti-Al reaction diffusion processes.Therefore,an in-depth understanding of Ti-Al reaction diffusion mechanism and kinetics will help to prepare Ti-Al intermetallic compounds and composites reasonably and efficiently.At present,Ti-Al reaction diffusion mechanism and kinetics have been extensively studied,but there are still many divergences on some conclusions.In part Ⅱ of this paper,the research progress of Ti-Al reaction diffusion kinetics involved in the preparation of Ti-Al intermetallic compounds and composites was reviewed,and the future research direction of Ti-Al reaction diffusion kinetics was prospected.
