Discussion

Analysis shows solution temperature affects microstructure and mechanical properties of AlSi37Cu alloy, indicating optimal processing parameters.

Hardness increased by 108.8% at 560 °C, while ductility decreased from 2.5% to 1.0%.
Electrical conductivity improved by 3.4% at 460 °C before deteriorating at higher temperatures.
Experimental analysis included rapid solidification and hot extrusion to define alloy characteristics.
Corrosion behavior highlighted a non-monotonic trend, emphasizing the need for optimal temperature selection.

Mao et al. (2025) studied this question.
