Abstract

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.

轻压铸用不同锰、镁含量AlSi10MnMg合金的力学性能

作品显示了选定的力学性能(HB;R $ \ mathbf {} _ {\ mathbf {m}}; \ \ \ mathbf {R} _ {\ mathbf {P}};A$)合金AlSi10MnMg不同Mn含量(0.4和0.6% mas);0.75%和1.0% ma)。用于交通运输行业的轻压铸件。给出了铸件和T6加工后的力学性能结果。结果表明:T6加工后试验合金的硬度为$105\div 118$ HB， $\mathbf{R}_{\mathbf{m}}$近似。$320\div $ 340$ MPa在T6之后，相对于浇筑后的情况(240 MPa)。对于AlSi10Mn0, 6MG1, 5合金(铸态)，T6处理后，$\mathbf{R}_{\mathbf{P}}$增大至140 Mpa，最大可达280 Mpa，也影响合金添加剂比例的增加。由此可以得出，在$\mathbf{R}_{\mathbf{P}}$合金AlSiMnMg添加量最大的方向为1.0 ~ 1.5% mas。Mg和大约0.6%的MAS。锰。延伸率约为5。在T6热处理后，约为8-9%(铸造状态)。
