【摘要】采用机械合金化方法制备了Fe80 Cu2 0 亚稳合金粉末 ,压制成片状后分别在 1 5 0℃、2 5 0℃、5 0 0℃进行了热处理 ,对 5 0 0℃处理的样品进行了低温电阻测量 .结果表理 ,样品的电阻表现为类似近藤效应的现象 .更多还原

【Abstract】 Meta-stable solid Solutions of Fe 80 Cu 20 was prepared by mechanical alloying of Fe and Cu powder blends.Heat treatment of the sample was performed at 150℃?250℃?350℃ and 500℃ respectively.The measuring results of low temperature resistance of the sample annealed at 500℃ was indicative of kondo effect.更多还原
