Abstract

Stabilization of Guinier-Preston zones (GP-zones), which have been found in an Mg97Gd2Zn1 alloy annealed at 200°C for 150 h, is studied. Single formation of the GP-zones without other precipitates is found in Mg98Gd1Zn1 and Mg97 5Gd1.5Zn1 alloys annealed at 200°C for 100 h. The GP-zones at this aging stage are distributed widely and separately from each other, but they change into many groups of band-shaped GP-zones by prolonged annealing.
