形成焓是描述合金形成能力和稳定性的重要参数。用亚规则模型对Ta-TM(TM=Ti,Cr,Co,Ni)二元合金的形成焓进行理论计算,目的是了解这四种Ta合金的热力学性质,预测其中间相的存在。结果显示亚规则模型对所研究的二元合金的形成焓结果能准确地描述和解释已有实验结果。这为制备和开发广泛应用于化学工业的耐腐蚀、航空航天工业的高温结构Ta合金材料提供了理论支撑。
The formation of enthalpy is an important parameter to describe the formation ability and stability of the alloy. The formation enthalpy of Ta-TM (TM = Ti, Cr, Co, Ni) binary alloys is theoretically calculated by the sub-rule model in order to understand the thermodynamic properties of the four Ta alloys and predict the presence of mesophase. The results show that the sub-rule model can accurately describe and explain the existing experimental results on the formation enthalpy results of the binary alloys studied. This provides theoretical support for the preparation and development of high temperature structural Ta alloy materials widely used in the chemical industry for corrosion resistance and aerospace industry.
