Discussion

Heat treatment enhances mechanical properties and microstructure in AlMn1Cu alloy, indicating improved ductility and reduced anisotropy.

Heat treatment at 300–340 °C improved ductility while reducing hardness and yield strength, enhancing the alloy's ease of shaping.
A notable decrease in anisotropy was observed, confirming effective homogenization of the microstructure in the aluminium alloy.
Changes in microstructure led to a fine-grained structure that supports high formability, viable for manufacturing applications.
This approach highlights the alloy's suitability for thin-walled components such as heat exchangers, benefiting industrial applications.

Zemlik et al. (2025) studied this question.
