The ultra-fine-grained microstructure of the AlSi7MgCu0.5 alloy is thermally stable up to 523 K, allowing for continued performance at elevated temperatures.
Mechanical properties of the alloy remained stable at temperatures up to 423 K, with noticeable strength reduction beyond this threshold.
Application of equal channel angular pressing resulted in high dislocation density and improved alloy strength due to strain hardening during processing.
Microstructural evaluations utilized synchrotron radiation X-ray diffraction and transmission electron microscopy to observe substructural changes.
