摘　　要：应用热分析,电阻和伦琴射线方法修正了Cu Pd合金相图,在300℃经过2200h热处理后,含Cu9%～32.5%(原子分数)范围内合金由α→α〃,含Pd35%～55%(原子分数)合金由α→β。这两个相区的最高有序 无序转变温度分别为510和655℃。The CuPd system phase diagram was amended by using thermal analysis, TEM, Xray diffraction and measurements of electrical resistance. It was found that under the heattreatment at 300 ℃ for 2200 h, the alloy transformed from α to α″, within the palladium compositions 9%～32.5%, and α to β, within the palladium compositions 35%～55%. The highest orderdisorder transformation temperature in there two phase areas is 510 and 655 ℃ respectively.
