摘　　要：研究了快凝Al92 3 Fe4 3 V0 7Si1 7Nd1 0 纳米晶合金薄带在电场时效过程中组织和力学性能的变化 ,并与等温时效处理结果进行比较 ,结果表明 :电场时效处理试样的相转变温度降低 ,力学性能有所提高。对电场作用机理进行了初步分析。The influence of an electric charge on the microstructure and mechanical properties during the aging of RS Al 92 3 Fe 4 3 V 0 7 Si 1 7 Nd 1 0 nanocrystalline alloy ribbon were studied. Compared with the result of isothermal annealing, the temperature of the phase transformation decreased and the mechanical properties increased. The effect of an electric charge was analysed briefly.
