components. Previous investigations indicated that magnesium alloys based on the Mg-Sc system exhibited interesting properties [2-4], and it was further found that the addition of Mn and Ce to Mg-Sc.... The average grain sizes for the Sc- and Zn-containing alloys are 153 μm and 196 μm, respectively. Based on the Mg-Ce, Mg-Ce-Mn and Mg-Mn-Sc phase diagrams [3, 13, 14] and combined......

, such as AZ91 and AM60 based on Mg-Al system, limit the application of these alloys to temperatures below 120 ℃[1]. Some magnesium alloys containing rare earth developed in past decades exhibit high... to develop some new magnesium alloys with good creep properties, acceptable castability and low cost. Recent investigations reveal that alloys based on Mg-Zn-Al ternary system are promising to meet......

Effect of Impurities and Cerium on Stress Concentration Sensitivity of Al-Li Based Alloys 田丽1,孟亮1 (1.College of Materials Science and Chemical Engineering, Zhejiang University, Hangzhou 310027, China) Abstract:A notch sensitivity factor was derived in order to evaluate the stress concentration sensitivity of Al-Li based alloys. The factor values for the Al-Li alloy sheets containing various......
: Magnesium based alloys with aluminum and zinc were obtained through electrochemical co-deposition from LiCl-NaCl-MgCl2 melt. The possibility of electrochemical co-deposition was discussed in detail...-deposition was also performed and certain compositions of the Mg-Al, and Mg-Zn were obtained. The alloys obtained from the co-deposition show a typical as-cast microstructure. The best conditions......
