MICROSTRUCTURE AND MECHANICAL PROPERTIESOF EXTRUDED PURE Mg WITH Bi ADDITION

Due to the increasing demand of low density and high strength Mg alloys for the automobile, railway, and aerospace industries, the exploration of cost-effective RE-free Mg alloys becomes more and more attractive. Instead of Mg-Sn based system, the Mg-Bi alloy system seems to satisfy this requirement as a potential candi*河北省教育厅高等学校科学研究计划项目QN2015035,河北省研究生创新项目220056,河北工业大学优秀青年科技创新基金2015002,河北省自 然科学基金优秀青年科学基金E2016202130,河北工业大学引进人才项目208002及科技部“中韩青年科学家”交流计划资助项目201510资助 收到初稿日期: 2016-01-26,收到修改稿日期: 2016-03-16 作者简介:孟帅举,男, 1990年生,硕士生 DOI: 10.11900/0412.1961.2016.00039
