Fig. 1. Photographs presenting part of the experimental procedure used in this research for preparing bulk MgH₂/10 wt% α-Ti₂Ni nanocomposite strips. (a) Ti₂Ni master alloy prepared using the arc melting technique, (b) as-synthesized metallic glass (MG)-Ti₂Ni ribbons, using melt spinning, (c) small shots of as-prepared snipped MG-Ti₂Ni ribbons, and (d) a cryo-mill operated under a flow of liquid nitrogen. The as-prepared cryo-milled nanocomposite MgH₂/10 wt% α-Ti₂Ni nanocomposite powders obtained after 25 h were charged into a stainless steel tube through a plastic funnel (e) and then cold rolled for 10 passes (f). The tube was then opened in the glove box to take out the cold rolled strips, which were straightened using cold rolling for 30 passes (g), to obtain straight strips 6.5–7 cm length (h).
