“…Mg 17 Al 12 precipitation mainly occurs in the Mg–Al binary phase, and it contributes to the strength of magnesium alloys. However, according to its phase diagram, the Mg 17 Al 12 phase in the AZ91 alloy is decomposed at a temperature of 643 K, and its decomposition temperature decreases as the composition reaches that of pure Mg [ 25 ]. Moreover, the thermal properties of precipitation phase such as Mg 17 Al 12 have been already investigated in our previous study [ 13 , 26 ].…”

Magnesium and its alloys have been restricted in their industrial applications due to problems related to their formability. To overcome this issue, controlling the crystallographic texture is important, and the texture formation mechanism should be investigated in relation to factors including deformation conditions and solute atoms. In particular, the effects of solute atoms on the texture formation behavior should be further analyzed because they can considerably affect the deformation behavior. Thus, in this study, to clarify the effect of aluminum concentration on the texture formation behavior and microstructure, high-temperature uniaxial compression tests were conducted on three types of AZ-series magnesium alloys (AZ31, AZ61, and AZ91). Compression was conducted at 673 K and 723 K, with strain rates of 0.05 s−1 and 0.005 s−1, up to a true strain of −1.0. Cylindrical specimens were prepared from a rolled plate that had a (0001) basal texture and was compressed parallel to the c-axis of the grains. Consequently, work softening and fiber texture formation were observed in all the specimens. During the deformation, the development of grain boundaries, which is a typical characteristic of continuous dynamic recrystallization (CDRX), was observed, and the (0001) texture was highly developed with increasing Al content. Although each alloy was associated with the same deformation conditions and mechanisms, the AZ31 alloy exhibited a non-basal texture component. The stacking fault energy contributed to the generation of slip systems and gliding, and it was seen as the main reason for texture variation.

“…However, the main problem with the combination of different metals is the difference in the chemistry of the materials, their melting points, thermal expansion, thermal conductivity, etc. [3]. Stainless Steels and Aluminium alloys aren't the only materials that may be used to decrease the weight of buildings in industries like shipbuilding and automotive, increasing productivity and reducing fuel consumption [4].…”

Several present day applications require joining of dissimilar materials by solid state processes. In this research work, two dissimilar metals – Aluminium and Steel were joined with a newly developed Friction Crush Welding (FCW) process. Macro-structure images along with X-Ray Diffraction (XRD) pattern were used to investigate the prepared samples. This work also aims to develop a novel Finite Element (FE) model based on ABAQUS for FCW of Aluminium-Steel materials. The numerical model was developed as a three-dimensional, explicit non-linear model utilising the Lagrange technique in ABAQUS. The developed FE model was validated by comparing the simulation results with experimental temperature data obtained by infrared thermography. The predicted temperature values from FE model are in excellent agreement with the experimentally measured values. The influence of welding variables, i.e., tool rotational speed (2000, 3000 and 4000 rpm) and welding speed (15, 30 and 45 mm/min) on temperature was also investigated. Results show that best weld structure is obtained when welding is performed at speed of 30 mm/min and tool rotational speed of 3000 rpm. The developed FE model of the FCW process may be used for predicting the temperatures and predicting the weld structure.

“…The welded structure of dissimilar metals not only makes full use of the excellent performance of the constituent materials, but also greatly reduces the overall production costs and significantly improves the economic benefit [1,2]. Therefore, it is widely used in mechanical equipment and components [3][4][5][6]. As we all know, titanium (Ti) and its alloys possess high specific strength and excellent corrosion resistance.…”

The dissimilar metal of Ti6Al4V and T2 were joined using a butt joint with and without an intermediate layer Ag by friction stir welding. The interfacial Ti–Cu IMCs of both joints are composed of Ti2Cu, TiCu and Ti3Cu4, and the thicknesses are about 1.5 μm and 3 μm, respectively. The intermediate layer Ag can promote the diffusion of Ti to Cu side, and the diffusion of Ti elements plays a dominant role in the formation of Ti–Cu IMCs. The joint with the intermediate layer Ag presents a higher tensile strength, which is about 70% of the Cu base metal. The fracture characteristics of both types of the joints are brittle fracture, but the tensile fracture regions are different.
