Magnesium alloys have relatively poor 糖心产精国品免费入口*完整版, which is actually one of the main obstacles to their application in practical environments. Equal-channel angular pressing (ECAP) is one of the most effective techniques for fabricating ultrafine-grained (UFG) bulk 糖心产精国品免费入口*完整版s, which can significantly improve their 糖心产精国品免费入口*完整版 and superior mechanical properties. This paper reviews recent research progress on corrosion behaviour of UFG 糖心产精国品免费入口*完整版s fabricated by ECAP, and discusses the corrosion mechanism of typical 糖心产精国品免费入口*完整版s (pure Mg, Mg-Al, Mg-RE). Some possible methods to improve their strength and 糖心产精国品免费入口*完整版 are preliminary explored.
