采用高能球磨方法研究了大变形条件下Nb-Ag合金的原子强制混合行为。结果表明,在这些高度不互溶的合金中,SPD可导致过饱和纳米晶固溶体的形成。Ag在Nb中的最大固溶度可达40-50 at.%但是Ag中的Nb被限制为小于10原子%。得到的富Nb相的稳态晶格参数显示出与Vegard定律相反的趋势。
Forced atomic mixing of Nb-Ag immiscible alloys under severe plastic deformation (SPD) were investigated by high energy ball milling of mixed elemental powders over a wide range of concentrations. The results show that SPD in these highly immiscible alloys can result in the formation of supersaturated nanocrystalline solid solutions. The maximum solubility of Ag in Nb reaches up to 40–50 at.% but Nb in Ag is limited to less than 10 at.%. The steady state lattice parameters of the obtained Nb-rich phases show an inverse trend to Vegard’s law.
