The microstructure , tensile properties , and creep behavior of Mg – Zn alloys containing 0 – 4 . 4 wt . % Zn

This paper describes the microstructure, tensile, and tensile–creep behavior of a series of Mg–Zn alloys ranging from 0 to 4.4 wt.% Zn. The microstructures consisted of equiaxed hexagonal-close-packed grains with fine precipitates preferentially located at grain boundaries. Some of the microstructures contained fine laths within the equiaxed grains. The finest grain sizes were observed for a Zn composition of 4 wt.%. Tensile experiments were performed at room temperature and 150 ◦C while creep experiments were conducted at 150 ◦C for applied stresses between 30 a t s e ©
