Abstract

Three-layer composite ingot of 4045/3004/4045 aluminum alloys was prepared by direct-chill semi-continuous casting process, the temperature field distribution near the composite interface, macro-morphology, microstructure and composition distribution of the composite interface were investigated. The results show that semi-solid layer with a certain thickness forms near the interface due to the effect of cooling plate, which ensures successful implementation of casting the composite ingot. Two different aluminum alloys are well bonded metallurgically. The mechanical properties of composite interface were measured, the tensile and shearing strengths of composite interface are 105 and 88 MPa, respectively, which proves that the composite interface is a kind of metallurgical bonding.

Evaluation of the mechanical properties and microstructure analysis of heat treated LM-12 alloy with SiO<inf>2</inf>and CNT hybrid metal matrix composites

In cases of well bounded composites, there are chances of alloy elements to diffuse over the boundary leading to no evidences of porosity. The boundary is comparatively improved by bonding force [7]. Researchers have carried out an experiment on the influence of heat treatment condition on aluminum alloy sheets for bending properties.
The current study is meant for LM-12 aluminium alloy reinforced with different weight percentage of SiO₂ and carbon nano tubes hybrid metal matrix composite development using stir casting method with sand mould technique. Further, heat treatment was carried out using ice quenching process for evaluating tests such as Microstructure analysis, Tensile strength and Hardness of Hybrid Metal Matrix Composite which were developed experimentally. Tests were performed on different specimens within the heat treated casting, according to ASTM standards. The microstructures of the composites were concentrated to know the scattering of the reinforcement particulates in Matrix. It has been observed that expansion of particulates essentially enhances tensile strength and hardness..
Deformation and heat treatment ability of three-layer 6009/7050/6009 Al alloy clad slab prepared by direct-chill casting
2018, Transactions of Nonferrous Metals Society of China (English Edition)
Three-layer 6009/7050/6009 aluminum alloy clad slab was fabricated by an innovative direct-chill casting process. To study the response of the clad slab to plastic deformation and heat treatments, homogenization annealing, hot rolling, solution and aging were successively performed on the as-cast 6009/7050/6009 clad samples. The results revealed that excellent metallurgical bonding between 7050 alloy layer and 6009 alloy layer was achieved under optimal parameters. The clad ratio obviously decreased when the annealed sample was rolled to 55% hot reduction level, and then changed slightly with further rolling. Furthermore, the content of rodlike Zn-rich phases increased significantly in 7050 alloy layer in the homogenized clad samples after rolling at 55%, 65% and 75% hot reduction levels, and the higher level of hot reduction resulted in narrower diffusion layer. Subsequent solution and aging significantly improved the hardness in 7050 alloy layer, interfaces and 6009 alloy layers of the rolled samples except for the thin side for the 75% hot reduction sample.
Microstructure and properties at bonding interface of AA4045/AA3003 aluminum alloy cladding billet prepared by semi-continuous casting
2016, Transactions of Nonferrous Metals Society of China (English Edition)
AA4045/AA3003 cladding billet was prepared by direct chill semi-continuous casting process. The macrostructures, microstructures, temperature distribution, compositions distribution and the mechanical properties at the bonding interface were investigated in detail. The results show that the cladding billet with few defects could be obtained by semi-continuous casting process. At the interface, diffusion layer of about 10 μm on average formed between the two alloys due to the diffusion of alloy elements in the temperature range from 596 to 632 °C. From the side of AA4045 to the side of AA3003, the Si content has a trend to decrease, while the Mn content has a trend to increase gradually. Tensile strength of the cladding billet reaches 103.7 MPa, the fractured position is located on the AA3003 side, and the shearing strength is 91.1 MPa, revealing that the two alloys were combined metallurgically by mutual diffusion of alloy elements.
