Intermetallic compounds which absorb large quantities of hydrogen have received considerable attention recently. The AB 2 laves phase intermetallic compound is known to be a potential material for hydrogen storage, owing to its large storage capacity, ease of activation and rapid reaction rate with hydrogen. In this work Al has been chosen as a substitute material for Cr and ZrCrAl ternary alloy is prepared using arc furnace. The mechanical alloying process has been introduced to produce nanocrystalline material. This paper presents comprehensive study on structural aspects of ball milled ZrCrAl alloy. On comparison of the XRD data, the broadening was found in the peak width with the increase of milling time which is clear indication of refinement of crystallite size. This refinement could also be confirmed from the SEM analysis also. PCT measurements were performed for a temperature range 303 K–373 K.
