The grain growth morphology, kinetics and texture change after uniaxial compression at 430 ℃ of an extruded AZ31 alloy were studied. The samples were loaded following two routes insuring two initial textures of the samples-with compression direction parallel and normal to the extrusion direction. For both initial textures, a stable grain size is attained upon isothermal annealing and the grain growth kinetics can be described by: dn=dnr+kt with an n value of around 15. The annealing texture with grown grains is a retained hot deformation texture without emerging or strengthening other components. Abnormal grain growth is not observed for annealing time up to 10 000 h at 450 ℃.
