Abstract
Abstract In this work high energy ball milling was used to prepare composite hydrogen storage alloy in the MmNi5−xMx–Mg system. X-ray diffraction and TEM analysis were used to characterise the microstructure of the composite alloy obtained by ball milling. It has been shown that the grain size of MmNi5−xMx and Mg components were reduced to nanometre range after about 20 h of milling. Besides, a Mm2Mg17 phase of nanometre size was also formed in the milling process. Thus, a composite alloy, referred to as nano-phase composite here, composed of MmNi5−xMx, Mg and Mm2Mg17 phase of nanometre size was obtained. Hydrogen storage behaviour of the nano-phase composite was compared with that of conventional MmNi5−xMx alloy by measuring PCT and kinetics. It showed that the hydrogen absorption properties were improved.
