Mechanical properties of the AlSi10MnMg alloy with a different content of manganese and magnesium intended for light die-casting

The work shows selected mechanical properties (HB; $\mathbf{R}_{\mathbf{m}};\ \ \mathbf{R}_{\mathbf{P}}; A$) alloy AlSi10MnMg with different Mn content (0.4 and 0.6% mas) Magnesium (0.5; 0,75 and 1,0% mas.) of the m.in. for light pressure casts for the transport industry. The results of the mechanical properties are presented for cast and after T6 machining. It Was found that: The hardness of the test alloys is $105\div 118$ HB after T6 machining, $\mathbf{R}_{\mathbf{m}}$ approx. $320\div 340$ MPa after T6 in relation to post-pour condition (240 MPa). The increase in the proportion of alloyed additives was also influenced by an increase of $\mathbf{R}_{\mathbf{P}}$ to 140 Mpa For alloy AlSi10Mn0, 6MG1, 5 (for casted State) and up to 280 MPA after T6 treatment. It can therefore be concluded that the most in the direction of increase $\mathbf{R}_{\mathbf{P}}$ alloys AlSiMnMg is additive 1.0-1.5% mas. Mg and approximately 0.6% of the MAS. Mn. Elongation is approximately 5. The, 5% (for casted state) and approximately 8-9% after the T6 heat treatment.
