| Description | The dislocation structure was analyzed in a Mg–4.98Al–1.46Ca (mass%) alloy using invisible criterion with transmission electron microscopy. Basal and non-basal segment of dislocation induced during die-casting is determined as much 〈a〉 and a few 〈a+c〉 dislocation. After the aging at 523 K for 10 h and tensile deformation at 473 K, only basal 〈a〉 dislocation can be observed. This dislocation structure is not observed in crept specimens, which support the difference in dominant strengthening mechanism between creep and tensile deformation.
