Abstract: This experimental work is focused on preparation of shape-memory Nano alloy using high energy ball mill (HEBM). Precise ball to powder proportion, working medium, and ball mill speed are cardinal factors which determine effectively of milling operation. In present work select material is micro size powder Zn, Cu, and Al of determined proportion of size 326 mesh and purit~99.5%, ball / powder ratio= 3/1 and rpm of planetary ball mill kept 300. In first step powder was dry milled up to 24 hours and samples were taken for X- ray diffraction, scanning electron microscopy, differential scanning calorimetric analysis. In presence of liquid nitrogen milling time drastically reduced with fine particle size reduction and feature. To get required characteristics, control of particle size is the most crucial phase in operation. Alloying by HEBM is an innovative technique, this technique facilitate adequate and effective control over changes at grain boundary level and external morphology by precise control over milling variables.
