摘　　要：在材料的制备、加工过程中,液—固相间润湿行为和界面间相互作用这一物理化学现象是常被提及的,因为对其研究不但在理论上有重要意义,在实际工程中也是必须考虑的关键因素,它对于材料制备的可能和材料形成的性能起到了较大程度的决定作用[1]。本实验研究以Al-Ti-C晶粒细化剂合成中的润湿反应行为及反应过程当中的合金组织形成机制为重点,通过润湿与反应条件的优化,选用液-固反应法成功制备Al-5Ti-0.25C中间合金基础上,通过OM和SEM等技术方法,系统分析了合成参数对其合金组织演化的影响规律,分析探讨了润湿与反应机制。The wetting of liquid on solid and interfacial interaction usually occur in the material fabrication and processing.Not only in theory,but also in practical engineering,it is also a key factor which must be considered.It plays a decisive role in the preparation of materials and the properties of materials.Wetting and interfacial interaction in some advanced materials and technologies were chosen as the research object in this study.The wetting problem is the essential problem in the preparing procedure of the Al-Ti-C grain refiner.So,the wetting reaction behavior and the synthesis mechanism of alloy microstructure in the process of preparation were researched as the important problems;The Al-5Ti-0.25 Cgrain refiner was prepared successfully through liquid-solidification reaction method while the wetting and reaction conditions optimized;The effect of different processing parameters on the development of alloy microstructures,the wetting and reaction mechanism were researched by using OM and SEM analytical methods.
