    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,有助于合理高效的制备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 through Ti and Al,such as TiAl3, γ-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 is reviewed, and the future research direction of Ti-Al reaction diffusion kinetics is prospected.
