Hydrogen absorbing alloy and method for its production

摘要

A hydrogen storage material which is characterized by having, as a cast alloy, a flaky or similar shape with a thickness of 50 to 500 mum and showing such crystallite orientation that the X-ray diffraction pattern has an intensity ratio of plane indices (002)/(200) of 2 to 10 as measured with the cooled surface of the flaky cast alloy being in parallel with a mount, and a process of producing the same.
