Abstract

This paper describes the microstructure, tensile, and tensile-creep behavior of a series of Mg-Zn alloys ranging from 0-4.4wt%Zn. The microstructures consisted of equaixed hexagonal-close-packed grains with fine precipitates preferentially located at grain boundaries. However, some of the microstructures contained fine laths within the equaixed grains. The finest grain sizes were observed for a Zn composition of 4wt.%. Tensile experiments were performed at room temperature and 150°C while creep experiments were conducted at 150°C for applied stresses between 30-50MPa. The greatest tensile and creep resistance was exhibited by Mg-4.1Zn which contained 0.2wt.%Y. The measured creep exponent for the Mg-4.1Zn alloy was 4.2 suggesting dislocation climb as the dominant creep mechanism. Overall, Zn proved to be a potent grain refiner and strengthener for Mg where 4wt.% appeared to be the optimal Zn content for tensile and creep strengthening over the range of alloying additions examined.
