Review：Mg and Its Alloy--Scope, Future Perspectives and Recent Advancements in Welding and Processing

摘要

This review article aims to analyze and evaluate the advantages, shortcomings, technological advancements and hereafter prospects in welding and processing of magnesium and its alloys. Studies have accounted that replacing other metals with Mg alloys will bring about in monumental weight reduction with significant addition in strength that could lead to dramatic transformation of metallic era of 21st century and onwards. However,wide application of Mg and its alloys depends on the development of advanced welding &joining technologies. The current paradigm and progress in welding,joining and processing of magnesium and its alloys are reviewed,and research trend in this field is briefly discussed.
