Abstract
The tensile properties and the indentation creep resistance of as-cast Mg-5 wt% Sn and Mg-5 wt% Sn-2 wt% Di alloys were studied in this paper. It has been shown that the tensile properties of Mg-5% Sn-2% Di alloy are comparative with that of AE42 alloy at room temperature and at 150 °C and 175 °C. The indentation creep experiments were conducted at 150 °C and 175 °C, suggesting that Mg-5% Sn-2% Di alloy has significantly better indentation creep resistance than AE42. The microstructure of Mg-5% Sn alloy is characterized by the presence of thermally stable Mg2Sn particles mainly along grain boundaries, and addition of 2 wt% Di to this alloy results in the appearance of new Sn-Di phase, which further significantly enhance the strength and creep resistance.
