Description
Summary:The Mg-Zn-MM alloy sheets produced by warm rolling processes were annealed at two different temperatures and mechanical properties and texture effect were evaluated. Few grains were observed in as-rolled sheets and the different grains size and orientations were analyzed in annealed sheets at 220 degree C, 380 degree C for 5min by electron back scattering diffraction. The heat treated sheet at 220 degree C showed the grain size of 4 mu m. The heat treated sheets at 220 degree C exhibited superior elongations to failure at room temperatures and the values of elongation to failure in the range of 100 degree C up to 350 degree C were found to around 2 times higher than those of commercially used AZ31 alloy sheet without the loss of tensile strength. The enhanced ductility was mainly stemming from the statistically recrystallized small grains which were initially developed and low recrystallized temperature. The details of deformation behavior of the alloy will be also presented.
