Abstract
Deformation behavior of a new Al-Zn-Mg-Cu-Zr alloy is investigated by dynamic upsetting compress test. The results show that, when the deformation temperature of Al-Zn-Mg-Cu-Zr alloy is below 350°C , there is dynamic precipitation behavior during deformation because of low temperature. Further deformation of the alloy will be difficult due to small precipitates in the alloy. When the deformation temperature is above 400°C , there is no dynamic precipitation behavior in the alloy. When the deformation temperature is higher than 450°C , there is dynamic recrystallization and size increase of grain. The results of dynamic upsetting test show that the appropriate forging temperature of Al-Zn-Mg-Cu-Zr alloy is range of 400-4201C , and the maximum deformation is 60%.关键词
