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
