| 摘 要： | 分别从机械合金化、等径角挤压、累积叠轧、往复挤压和高压扭转等制备技术出发介绍了大塑性变形制备超细晶储氢材料的研究进展,认为块体机械合金化技术在制备储氢材料方面比传统球磨技术更具优势,提出弄清纳米材料的储氢机理是大幅度提高吸放氢性能的关键,开发储氢性能优异材料的同时要兼顾其力学性能.

| Abstract: | Research progress in fabricating ultrafine-grained hydrogen storage materials by severe plastic deformation is introduced according to five preparation techniques including mechanical alloying, equal channel angular pressing, accumulative roll-bonding, reciprocating extrusion and high pressure torsion. It is considered that bulk mechanical alloying techniques possess more advantages in fabricating hydrogen storage materials than traditional ball milling technique. Making clear hydrogen storage mechanism of ... |
