| Outline of Final Research Achievements |
In this study, Ca element with a flame-retardant property was added into Mg-Al and Mg-Zn magnesium alloys, and the resulting microstructures, mechanical properties as well as stretch formability of rolled sheets were investigated. As a result, texture-controlled flame-retardant magnesium alloys with excellent room-temperature sheet formability were achieved under proper rolling conditions and optimal alloying compositions. In addition, the changes in microstructure and texture during annealing was investigated for rolled Mg-Zn-Ca alloy. The formation process of the unique texture with about 35° inclined basal poles toward sheet transverse direction, which is beneficial for enhancing sheet formability, was revealed.
