Hydrogenation of nanocrystalline Mg2Ni alloy prepared by high energy ball-milling followed by equal-channel angular pressing or cold roiling

摘要

Nanocrystalline Mg2Ni powders produced by high energy ball milling (HEBM) were subjected to further severe plastic deformation by cold rolling (CR) or equal-channel angular pressing (ECAP). The microstructure of the alloys have been analysed by the Convolutional whole profile fitting method of the X-ray line profiles. The hydrogenation behavior has been studied by absorption kinetic measurements.
