Effect of Cold Rolling on Metal Hydrides

摘要

In this paper we review the recent studies of the effect of cold rolling on selected metal hydride systems. Magnesium is the most studied element in this perspective either as pure element, alloys, allied with iron or in a composite with AB(5) alloy alloys. Other systems will also be discussed such as titanium, AB(5) and AB(2) systems. After a critical review of these systems, we will discuss in detail the effect of cold rolling on Mg2Ni alloy and shows that cold rolling is efficient to improve the first hydrogenation but has basically no impact of subsequent hydrogenation kinetics.
