摘要：
In this text, 5083 aluminum alloy was prepared with the method of the liquid nitrogen cryogenic milling (cryomilling) The microstructure,microstructural evolution and thermal stability of sample powder was investigated by XRD, SEM and DSC The experimental results show that the particles size of 5083 aluminum alloy power during cryomilling was gradually reduced; milling time and milling speed are: the main factors of affected alloy structure and performance, and high speed cryomilling could result in more uniform nanometer grains The microstructure of the cryomilline 5083 aluminum alloy for 5 hours is micron-sized agglomerates with an average grain size of 45 nm.
