摘要	Nanocrystalline Al-Zn-Mg-Cu alloy powders have been sucessfully fabricated by mechanically milling at cryogenic temperature (cryomilling) in liquid nitrogen. Microstructural evolution of the alloy powders during cryomilling was analyzed. The experimental results show that the as-atomized Al-Zn-Mg-Cu alloy powder size was gradually reduced and approached 35 nm after 15 h cryomilling. MgZn2 phase gradually disappeared and ultimately was super-saturated into alpha-Al. No significant grain growth for the nanocrystalline Al-Zn-Mg-Cu alloy was found when it was heated at or below 709 K, for example, the average grain size of the milling alloy heated at 709 K for 1 h is only 71 nm. The results obtained herein suggest that the significant thermal stability of the cryomilled Al-Zn-Mg-Cu material may be attributed to the presence of nano-scale Al2O3 particles.
