Al-Mg alloys are normally prone to lose part of their yield and tensile strength at high temperatures due insufficient thermal stability the microstructure. Here, we present a Ca-modified Al–Mg–Sc alloy demonstrating elevated temperatures. The microstructure contains Al4Ca phases distributed as network along grain boundary Al3(Sc,Zr) nano-particles dispersed within grains. evolution age-hardeni...

A356 cast aluminum alloy contains 7 at.% Si and 0.3 Mg, producing an approximately 50% eutectic microstructure. This high content various casting conditions play a significant role in strengthening alloy, by controlling the morphology precipitates of other intermetallic compounds. Understanding how Si-related clusters are soluble α-matrix is necessary to provide strength fatigue resistance allo...
