热压Ag-Cu复合材料的界面层两侧各为含Ag的Cu基固溶体和含Cu的Ag基固溶体。界面两侧的结合是固溶体间的金属结合,界面强度比纯Ag的强度略高,而比纯Cu的强度低。 本文用X射线方法测定界面层晶格参数,用拉仲方法测定界面强度,并用Seah的准化学方法计算界面强度,与实验结果一致。研究结果表明,采用热压工艺制备Ag-Cu复合材料可以实现Ag-Cu的牢固结合。
The interracial structure and cohesion strength of Ag-Cu bimetal composite material, obtained by hot-prossing, has been examined. X-ray diffraction patterns show that a binary solid solution containing Ag or Cu respectively is found on each side of the interface. The fracture surface of the tensile specimen made of such bimetal composite material lies on the Ag side of the interface, and the interface itself does not split. The Seach's quasi-chemical method, which is modified to evaluate the cohesion strength of the bimetal interface, gives the theoretical strength of 287.5 MN/m~2, which is higher than that of pure Ag. This is in agreement with the experimental observations. It seems to be concluded that the hotpressing is available to produce a stronger interracial cohesion of such bimetal composite material.
