title = "Preparation and microstructure of nanocomposite Mg-3Al-Zn alloy by HDDR combined with ball milling",
abstract = "Nanocrystalline Mg-3Al-Zn alloy was synthesized by ball milling of elemental powders of Mg, Al and Zn under hydrogen atmosphere. The powders of Mg, Al and Zn were mechanical alloying and disproportionated by ball milling under hydrogen and desorption-recombination was then performed. The structural changes due to both the milling in hydrogen and the subsequent desorption-recombination treatment were characterized by X-ray diffraction (XRD). The desorption-recombination behavior of the hydrogenation alloy was investigated by differential scanning calorimetry (DSC). The morphology and microstructure of the final alloy powders subject to desorption-recombination treatment were observed by SEM, TEM and HRTEM, respectively. The results showed that, by milling in hydrogen for 60 h, the Mg-3Al-Zn alloy was disproportionated into nano-structured with average size of about 50-60 nm, and a subsequent desorption-recombination treatment at 320°C for 30 min didn't change the average crystallite size of the powders.",
