Computer simulation of γ′ and θ phase precipitation of Ni-Al-V alloy using microscopic phase-field method LI Yong-sheng(李永胜), CHEN Zheng(陈 铮),WANG Yong-xin(王永欣), Lu Yan-li(卢艳丽) (School... and some are even larger than those remained. Our study is consistent with the critical nucleus of δ′(Al3Li) phase studied by LI et al[17]. But the γ′ phase dose not have this phenomenon. In order......

the problem of oxidation and poor wetting[4-6], new Sn-Zn based alloys are still under development. Lin et al[7, 8] have reported that adding Ag or Al to Sn-9Zn alloys can accelerate their wetting on Cu substrate. Yu et al[9] and Xie et al[10] have demonstrated the effect of Re and Cu on the wetting behavior on Cu substrate of Sn-Zn based solders. The wettability of Sn-9Zn base alloys can be improved......
prepared via microemulsion approach. For example, Wang et al[11] reported the preparation of α-Fe nanoparticles by a microemulsion system consisting of saturated Fe2+ solution, isopropanol and PVP; Chen et al[1] synthesized colloidal gold nanoparticles by a reverse microemulsion system consisting of CTAB, n-pentanl, hexane and water; Caponetli et al[2] prepared CdS nanoparticles by a microemulsion......
