Thermodynamic Assessments of Phase Equilibria in some (Cu,Ni)-based ternary alloys
Abstract
Cu基合金具有高强高导等一系列优良性能，科研工作者一直致力于对该类合金的研发工作，但是利用两相分离的特殊性能进行开发还比较少；Ni基合金的主要应用领域为高温合金，在钎焊领域也发挥着重要作用，Ni基钎料有许多卓越性能，例如耐高温、耐腐蚀、抗氧化等性能，多应用于不锈钢和多种高温合金的钎焊。作为材料设计的重要理论依据，相图在金属材料的成分设计中发挥着十分重要的作用。因此，开展(Cu，Ni)基三元合金系相图的热力学计算，具有很大的研究价值。本论文主要采用CALPHAD方法，对部分(Cu，Ni)基三元系合金的进行了热力学计算，所取得的主要研究成果如下： （1）收集整理基础二元系的参数和三元相平衡实验信... Copper-based alloys have the strengths of high strength as well as high conductivity, the researchers have always been engaged in the research of them. At present, in the use of the characteristics of phase separation, the work of designing new Copper-based alloys is limited. Nickel-based interlayers are widely used for their good anti-high temperature, good anti-cauterization, good anti-oxidatin ...
