The alloys containing 3.8 at%, 7.2 at% and 14.5 at% hydrogen were prepared and were comminuted with a ball mill. The particle size distribution of the powders was measured by screen analyses, and microscopic observation of the particle shape was carried out.The main results obtained are as follows:(1) The alloys are brittle enough to be comminuted readily.(2) Cracking and fragmentation of the alloys are enhanced by thermal cycling in the hydrogenation process.(3) With increasing the hydrogen content in the alloys, a higher percentage of fine particles is obtained.(4) Particle shape varies with the hydrogen content of the alloys. Rounded or irregular particles are obtained from the lower concentration alloys and acicular or angular particles from the higher concentration alloy.
