用点阵参数法测定了熔体淬火条件下过渡金属Fe,Co,Ni,Cr,Mn和Zr在Ag中固溶度的扩展。在10~5-10~6K/s冷却速度下,它们在Ag中亚稳极限固溶度C_(eq)~s分别为1.0,1.5,1.5,3.0,48和6at.-%。提出了不同的亚稳扩展机制,讨论了共晶系,包晶系和偏晶系三种类型Ag合金系亚稳扩展的规律,并用表面张力理论和元胞电子密度说明和描述了偏晶系合金液态溶解度和亚稳固溶度的规律。
The solid solubility of transition metals Fe, Co, Ni, Cr, Mn and Zr in Ag melt was measured by the lattice parameter method. At 10 ~ 5-10 ~ 6K / s cooling rate, their metastable limit solubility in C_ (eq) ~ s were 1.0,1.5,1.5,3.0,48 and 6at .-%. Different metastable expansion mechanisms are proposed. The regularity of metastable expansion of three types of Ag alloys, including eutectic, peritectic and metaocrystal systems, is discussed. The surface tension theory and the cell electron density are used to describe and describe the metastable system. The law of liquid solubility and metastable solid solubility of alloy.
