Heat treatment is widely used to improve the properties of Al–Si–Mg alloys and its outcomes are influenced by the parameters applied during the treatment. This study describes the effect of the solution and artificial aging treatments on the microstructure and mechanical properties of die-cast Al–Si–Mg alloys. The microstructure of the as-cast Al–Si–Mg alloy was mainly composed of α-Al, complex needle-type eutectic Si particles, Mg2Si, and α-AlFeMn. The complex needle-type eutectic Si particles disintegrated into spheroidal morphologies, while the Mg2Si was dissolved due to the solid solution treatment. The maximum yield strength (YS) and ultimate tensile strength (UTS) values were 126.06 and 245.90 MPa at 520 °C after 90 min of solution heat treatment, respectively. Although the YS and UTS values of the Al–Si–Mg alloys reduced due to the solution treatment, the elongation (EL) of the solid solution heat-treated Al–Si–Mg alloys was improved in comparison to that of the as-cast Al–Si–Mg alloy. The maximum YS and UTS of 239.50 and 290.93 MPa were obtained after performing artificial aging at 180 °C for 180 min, respectively. However, the EL of the aging heat-treated alloy was reduced by a minimal value.

“…Then, the (Al + Si) structure eutectic formed substantially. Compared with the as-cast AlSi12 microstructures [24], both the primary dendrites and eutectic structures were refined. The reason for the refinement of microstructures can be attributed to the rapid cooling rate caused by the lower heat input and fast heat dissipation of the steel plate.…”

AlSi12 cladding layer was fabricated on steel plate without zinc coating via cold metal transfer arc deposited technique. The wettability, morphologies, microstructures, and mechanical properties of the cladding layer were investigated. The cladding layer exhibited favourable wettability with steel plate. Large swing amplitude and high swing frequency were the key factors to achieve excellent wettability. The cladding layer was composed of primary Al dendrites and (Al + Si ) eutectic structure, and the microstructures were refined. Continuous and thin intermetallic compound layer appeared at AlSi12/steel interface, and reliable bonding strength between the cladding layer and steel plate was achieved. The fracture surface exhibited both brittle fracture and ductile fracture.

“…Notably, the additional battery costs required to achieve an equivalent range are significantly higher [ 5 , 6 ]. Die-cast aluminum alloys are more prevalent in automotive manufacturing than wrought aluminum alloys, making the development of aluminum alloy die-casting technology and its associated heat treatment processes a crucial area of research [ 7 , 8 , 9 , 10 ]. High-quality AlSi10MnMg aluminum alloy castings are extensively used in manufacturing automotive structural components, such as housing towers, longitudinal carriers, and transverse bearing beams [ 11 , 12 , 13 , 14 ].…”

This study investigates the artificial aging treatment process for AlSi10MnMg longitudinal carriers with optimal strength and ductility. Experimental results illustrate that the peak strength is observed under single-stage aging at 180 °C × 3 h, with a tensile strength of 332.5 MPa, Brinell hardness of 133.0 HB, and elongation of 5.56%. As aging time increases, tensile strength and hardness initially increase and then decrease, while elongation displays an inverse pattern. The amount of secondary phase particles at grain boundaries increases with aging temperature and holding time, but stabilizes as aging progresses; the secondary phase particles begin to grow, eventually weakening the alloy’s strengthening effect. The fracture surface exhibits mixed fracture characteristics, including ductile dimples and brittle cleavage steps. Range analysis indicates that the influence of distinct parameters on mechanical properties post-double-stage aging is as follows: first-stage aging time, first-stage aging temperature, followed again by second-stage aging time, and second-stage aging temperature. For peak strength, the optimal double-stage aging process includes a first-stage aging temperature of 100 °C × 3 h and a second-stage aging temperature of 180 °C × 3 h.
