摘要: Abstract The ball to powder ratio (BPR) is a processing parameter that frequently used in both mechanical (ball) milling and alloying. A number of recent studies provided the BPR as principal while neglecting other parameters, such vial volume, diameter quantity balls mass. In this experiment, different batches magnesium hydride were milled using varying size, mass, parameters constant BPR. hydrogen desorption properties (i.e., differential scanning calorimeter) phase evolution XRD analysis) powders subsequently investigated. obtained results demonstrated cannot be single parameter. DSC curves during decomposition with rate 5 °C/min revealed significant differences peak temperature among samples same Additionally, patterns crystallite size after varied, suggesting existed effectiveness process.
