机械合金化过程中各种因素对储氢合金结构和性能的影响

Effect of different factors on the microstructure and hydrogen storage property of alloy in ball-milling process

机械合金化是最近发展起来的制备储氢材料的新型工艺,在改善材料结构和储氢性能方面显示出非常有效的作用。然而,在机械合金化过程中的各种因素,包括球磨时间、球磨环境、球料比等,对合金的结构和储氢性能有不同程度的影响。综述了国内外在机械合金化方面的研究,为更进一步探索通过调整这些因素来改善储氢合金性能有一定的指导意义。

In present,mechanical alloy（MA） has become extremely promising technology regarding synthesizing hydrogen storage alloy.The technology can improve effectively property of alloy,however the grinding time,balling atmosphere,ball-to-powder and so on affect the misrostructure and hydrogen storage performance of alloy to varying degrees.This paper summarizes mainly research conclusions at home and abroad,providing reference for further investigating hydrogen storage alloy by adjusting these factor.
