ABSTRACT:
A hydrogen occluded alloy and a process for producing the above alloy are disclosed. The above process mechanically forms the hydrogen occluded alloy having improved initial discharging characteristics. In the above process, either a powdered LaNi.sub.5 alloy or rare earth metals, such as la, Ce, Pr and Nd, and a powdered CaCu.sub.5 alloy of Mm-Mn-Ni-Al-Co alloys is mixed with a powdered Laves alloy of Zr-Mn-V-Cr-Ni alloys into a powdered alloy mixture. Thereafter, the alloy mixture is applied with a mechanical impact by a high energy ball mill with an attritor, thereby mechanically forming the hydrogen occluded alloy. The above process easily controls the manganese component while producing the hydrogen occluded alloy through the mechanical alloying.
