The effect of nickel on surface energy of the solid/gas interface of silver was studied. The measurements were taken using foils according to the previously developed in situ method in an atmosphere of Ar + 10% H₂ at high temperatures. This method simultaneously allows one to determine the surface energy and diffusion creep rate. The solubility of nickel in silver is very low, so the measurements were taken for the alloys in the two-phase region with 0.45 at.% Ni and 1.5 at.% Ni, as well as for pure nickel. Nickel is shown to significantly increase the surface energy of silver and slow down the diffusion creep rate.

镍对固体银表面能和扩散蠕变的影响

研究了镍对银固/气界面表面能的影响。根据箔片根据先前开发的原位方法在高温的Ar + 10％H ₂气氛中进行测量。该方法同时允许确定表面能和扩散蠕变速率。镍在银中的溶解度非常低，因此对含0.45 at。％Ni和1.5 at。％Ni的两相区域的合金以及纯镍进行了测量。镍被证明会显着增加银的表面能并减慢扩散蠕变速率。
