主　　题：Magnesium alloy Scrap recycling Recycling techniques 

摘      要：Magnesium(Mg)alloy is widely used in aerospace and automotive industries as an excellent lightweight metal material to reduce carbon *** expansion of Mg alloy applications and the increasing demands for these materials have significantly facilitated the generation of Mg alloy *** recycling of Mg resources is crucial for promoting both environmental sustainability and economic ***,current recycling effect is ***,this paper provides a comprehensive review of the entire recycling process,including scrap classification,separation and sorting,pre-treatment,and *** paper explores the generation of Mg alloy scrap and its reincorporation into industrial *** review outlines various Mg scrap recycling technologies based on different phase *** include liquid-state recycling(such as flux refining,impurity removal additives,fluxless refining,compound treatment,and direct remelting),solid-state recycling(involving hot extrusion,equal-channel angular pressing(ECAP),friction stir extrusion(FSE),and spark plasma sintering(SPS)),vapor-state recycling(comprising vacuum distillation and sublimation),electrochemical recycling(solid oxide membrane(SOM)electrolysis,RE-12TMelectrorefining,and non-aqueous solution electrorefining),and Mg secondary alloy *** advantages and existing challenges associated with each method are compared and discussed,and the current obstacles to the future recycling of complex scrap are examined.
