用水雾化法制备了铜铬和铜铬锆合金粉末，并用温挤压法进行了固结。共格铬的析出与合金的峰值硬度条件有关。时效处理后获得的力学性能，即峰值硬度和相应的验证应力与合金元素在粉末中的初始固溶体浓度有关。用析出强化和弥散强化理论解释了观察到的强化，并与以前文献中报道的这些合金系统的类似分析进行了比较。版权所有(C)1996 Acta Metallurica Inc.
Cu-Cr and Cu-Cr-Zr alloy powders were produced by water atomization and consolidated by warm extrusion. Coherent Cr precipitation is associated with the peak hardness condition in these alloys. The mechanical properties obtained after ageing treatments, namely the peak hardness, and the corresponding proof stress are related to the concentration of the alloying element initially in solid solution in the powders. The strengthening observed is interpreted in terms of theories of precipitation and dispersion strengthening and compared with similar analyses reported previously in the literature for these alloy systems.
