Key Points
Manganese enhances tensile strength and electrical conductivity in Al-Mg-Si alloys, optimizing overall performance and making them more effective for various applications.
The as-cast Al-0.6Mg-0.58Si-0.24Fe-0.18Mn alloy showed a tensile strength of 176 MPa and conductivity of 48.07 %IACS, revealing excellent material properties.
Observational analysis focused on microstructure and property optimization, illustrating manganese's role in resistivity variations and phase modifications.
Support from Matthiessen’s rule indicates manganese's primary contribution to resistivity, with less impact from dislocations and grain boundaries among the studied alloys.
