The beta phase of nickel and cobalt aluminides with B2-type (C_sC1) structure have the potential to serve as a new type of materials with multi-functional properties such as high temperature strength, good oxidation resistance, shape memory, high damping capacity, stc. However the lack of ductility limits their application as the functional materials. The aim of this project is to develop a new type of beta base multi-functional materials improved ductility by microstructural control.1.Thermodynamic AnalysisThe phase equilibria of the Ni-rich portion in the Ni-Al-Mn, Ni-Al-Co and Ni-Al-Fe systems have been experimentally determined, and thermodynamic analysis on basis of the experimental data have been done.2.High Temperature MaterialsBy means of microstructural control due to the information of the thermodynamic analysis, ductile gamma'(L1_2)+beta two-phase alloy which has both excellent oxidation resistance and high temperature strength has been developed by the conventional fabrication method combined with a thermomechanical heat treatment.3.Shape Memory and Damping MaterialsMartensitic transformation temperatures in the beta phase B2*L1_0 (Ms) of the Ni-Al-X (X : Ti, V,Cr, Mn, Fe, Co, Cu, etc.) systems were determined by DSC.It was clarified that adding Mn, Fe and Co are useful to increase the Ms temperature. By means of these data of Ms and phase equilibria, ductile gamma(Al)+beta two-phase shape memory alloys which operate at high temperatures between 100 and 600ﾟC have been developed in the Ni-Al-Fe-Mn quaternary system. These two-phase shape memory alloys show not only high damping capacity, but also higher yield strength than the other damping materials.

具有B2型(C_sC1)结构的镍钴铝化物β相具有作为新型材料的潜力，具有高温强度、良好的抗氧化性、形状记忆、高阻尼能力、stc等多功能特性。然而，缺乏延展性限制了它们作为功能材料的应用。该项目的目的是开发一种新型β基多功能材料，通过微观结构控制提高延展性。1.热力学分析。通过实验确定了Ni-Al-Mn、Ni-Al-Co和Ni-Al-Fe体系中富Ni部分的相平衡，并根据实验数据进行了热力学分析。2.高温材料通过热力学分析信息的显微组织控制，结合传统制造方法，开发出兼具优异抗氧化性和高温强度的延性γ'(L1_2)+β两相合金。 3.形状记忆和阻尼材料Ni-Al-X（X：Ti、V、Cr、Mn、Fe、Co、Cu等）β相B2*L1_0（Ms）的马氏体转变温度.)系统通过DSC测定。通过Ms和相平衡、延展性的这些数据表明，添加Mn、Fe和Co对于提高Ms温度是有用的。在 Ni-Al-Fe-Mn 四元系中开发出可在 100 至 600°C 高温下工作的 γ(Al)+β 两相形状记忆合金。这些两相形状记忆合金不仅具有高阻尼性能。容量，而且比其他阻尼材料具有更高的屈服强度。
