Analysis of the microstructural evolution and solidification behaviour of Sn-9 wt% Zn alloy with small additions of Mg [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2013
The microstructure, solidification behaviour and hardness of Sn-9Zn-xMg (where x = 0, 0.5, 2.5 and 5 wt%) alloys were studied. The addition of 0.5 wt% did show a clear effect on the microstructure, producing three distinctive zones: a) fine ...
