摘要：

Gas atomized Al88Ce8Fe4 alloy powders were ball-milled and investigated at charge ratios of 5:1, 15:1 and 30:1 and milling speeds of 150 and 200 [RPM], respectively. The morphology, microstructure and composition of the powders were examined by laser diffraction technique, SEM, EDS and XRD. The result indicates the evolution of the powders under milling experiences initially cold welding, aggregating the powders into larger-sized disk-shaped particles; followed by fragmentation, forming smaller-sized equiaxed particles; and finally leading to a steady state, where particles morphology, composition and phases keep constantly unchanged. This procedure has been testified as a general rule for milling at each of the charge ratios of 5:1, 15:1 and 30:1 and at milling speeds of 150 and 200 [RPM] while milling at larger charge ratios or higher speeds drives faster to reach the steady state at which homogeneous, fine-sized glassy powders can be obtained. © 2018 Trans Tech Publications, Switzerland
