“…It is known that T6 heat treatment (solution and aging treatment) has a great influence on the precipitation strengthening for Al-Si-Mg alloys. The ultimate tensile strength, yield strength, and elongation of the T6-treated AlSi7Mg alloys are both improved due to the equiaxed of Si particles and the hardening of Mg2Si precipitation [5][6]. The strengthening is attributed to the combining effect of fine particle and precipitation strengthening [7].…”

The effects of the heat treatment process parameters on the microstructure and mechanical properties of a selective laser melted (SLMed) AlSi10Mg alloy were systematically investigated. The SLMed AlSi10Mg alloy was treated with T1 (180°C× 4h + air cooling) process, which had the microstructure of fine α-Al grains, fine Si phase, and nano-sized precipitations. The microhardness significantly increased to 150 HV, which is even higher than as-SLMed one (126 HV). The microhardness of SLMed AlSi10Mg alloy treated with T4 (540°C × 2h + water cooling) heat-treatment process significantly decreased to 62 HV due to the growth of α-Al grains, Si phase and the formation of β-AlFeSi phase. However, the microhardness and ultimate tensile strength of AlSi10Mg alloy treated with T6 (540°C × 2 h water cool + 180°C × 4 h air cool) process decreased to 91 HV, although the strengthening precipitation of Mg2Si phase formed. It indicates that the Mg2Si phase cannot compensate for the adverse effect of grain growth. It may provide the best potential heat treatment method for fabricating the high strength SLMed AlSi10Mg alloy.

“…So far, there are many processes for manufacturing Al/Mg composites, such as diffusion welding [ 7 , 8 ], friction stir welding [ 9 , 10 ], explosive welding [ 11 , 12 ], gravity composite casting [ 13 , 14 ], lost mode composite casting [ 15 ], rolling [ 16 ] and solid-liquid casting and rolling combination [ 17 ]. Solid-liquid cast-rolling bonding (SLCRB) is a novelty method in which the liquid metal is poured on the surface of the solid metal, and then both are sent to the rolling mill together.…”

An Al 6061/Mg AZ31B composite plate with good bonding and excellent comprehensive mechanical properties was prepared through solid-liquid cast-rolling bonding (SLCRB). The microstructure evolution and mechanical behavior of Al/Mg composite plates under different rolling passes were studied. The results showed that with the increase of rolling passes, the bonding layer of the composite plate was crushed, and the base material on both sides of the substrate gradually grew towards the broken part of the bonding layer. The microstructure on both sides of the substrate extended along the rolling direction and was dynamically recrystallized to a certain extent. In the Mg substrate, because the preheating temperature was higher than its recrystallization temperature, with the increase of rolling passes, the grains in Mg substrate were crystallized. When the rolling passes reached the fourth pass, complete recrystallization basically took place in the Mg substrate. With the change of the internal structure and bonding layer on both sides of the substrate, the mechanical properties of the composite plate can be improved gradually. The tensile strength increased from 136 MPa before rolling to 190 MPa at the fourth pass, and the shear strength increased from 74 MPa to 98 MPa, with growth rates of about 40% and 32%, respectively. The elongation of the composite plate decreased from 6.3% to 5.4%, a decrease of about 1%.

Effect of Annealing Process on the Microstructures and Mechanical Properties of AZ31B/A356 Composite Plate Fabricated by Cast Rolling

Abstract: The shear strength reaches a maximum value of 116 MPa when the annealing temperature is 200 ºC. Cleavage fracture occurs at the side of the AZ31B alloy and quasi-cleavage fracture at the side of the A356 alloy.
