Studies of the effect of melt spinning on the electrochemical properties of the AB2 Laves phase alloys

A comparative study of the effect melt spinning on electrochemical properties C14 and C15 AB2 alloys has been performed. The wheel speeds 630, 2100, 4100 cm/s were applied during rapid solidification both alloys. structural analysis formed phases was performed by X-ray powder diffraction (XRD), while their microstructural morphology studied scanning electron microscopy (SEM). In a tremendous grain refinement due to process observed: addition, also significantly contributed morphological variation changes in which showed from equiaxed at lower speed small dendrites higher speed. contrast alloys, not observed for Furthermore, melt-spun 2100 maximum capacities 435 414 mAh/g achieved, respectively. As revealed significant spinning, an increase capacity achieved. However, parameters need be further optimized improve poor activation behavior rapidly solidified
