Unexpected influence of Mn addition on the creep properties of a cast Mg–2Al–2Ca (mass%) alloy
Source abstract
Abstract
Abstract The addition of 0.3% Mn to a Mg–2Al–2Ca (mass%) alloy improves the minimum creep rate by one order of magnitude compared with the Mn-free alloy. Network-shaped Mg 2 Ca (C14 structure) and (Mg,Al) 2 Ca (C36 structure) compounds coexist in the interdendritic regions, while plate-shaped Al 2 Ca (C15 structure) phases are dispersed in the matrix. Ordered Guinier–Preston (GP) zones form dynamically on the basal plane of the α-Mg matrix during creep deformation. The number density of the fine GP zones in the Mn-containing alloy was found to be higher than that in the Mn-free alloy.
