Abstract：The effect of various regimes of heat treatment on the resistance and ther- moelectromotive force of AuPd_(38.6)Cr_3 and AuPb_(36.6)Cr_8 alloys as well as the rela- tionship between their properties and structure have been investigated.The room temperature resistivity of these alloy specimens after annealing at different tem- peratures increases and maximizes at 450 and 850℃,but decreases with cold wor- king.As the cold worked specimen aged at 400 and 480℃ two peaks were ob- served on the resistivity plot and X-ray relative intensities vs time curve,while two plateaus were found on the thermoelectromotive force curve.All the pheno- mena appear correspondingly on the time axis.It seems that this anomalous behaviour is closely related to the special clusters forming in the super-saturated solid solution. 收稿日期: 1987-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 何华春 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I1/63 1 何华春.金属学报,1981;17:97 2 Mott N F.J Inst Met,1937;60:267 No related articles found!
