Abstract Scope |
Recrystallization kinetics of magnesium alloys can vary greatly based upon precipitate and solute content. Rare earth alloying elements, such as Ce, have been shown to improve the elevated-temperature properties of magnesium alloys. Quantifying the effects of precipitate fraction and solute content can result in fundamental understanding that will enable optimized industrial processing pathways. The baseline composition for this study is ZK60, with modified zinc and cerium additions. These alloying modifications result in variations in second phase insoluble particle type, volume fraction and distribution that have strong effects on both grain size and recrystallization. Here, we present quantitative determinations of precipitate and solute content as a function of alloying and relate these aspects to recrystallization kinetics. These results provide further insights into mechanical and microstructural characteristics, such as grain size distribution, texture, and hot working flow stress, which are affected by enhanced or retarded recrystallization kinetics. |
