Florin Popa等人将元素粉放入行星式球磨机中,在氩气氛下球磨28h,每隔一定时间取样,用X-射线检测合金相的变化情况,发现经16h球磨后的合金,出现B2结构的Ni_2MnSn和C_(1b)结构的NiMnSn两种相
Florin Popa et al. Put the elemental powder into a planetary ball mill and ball milled for 28 hours in an argon atmosphere. Samples were taken at regular intervals and alloy phase changes were detected by X-ray. It was found that the alloy with B2 structure Ni2MnSn and C_ (1b) structures of NiMnSn two phases
