A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Critical Factors Governing the Frictional Coefficient in Mg Alloys—Learn From Machine Learning
Machine learning models were successfully used to predict the friction coefficient of Mg alloys based on composition, processing, mechanical properties, and tribological parameters. Normal load, elastic modulus, and Zn content are the most important factors in governing the friction coefficient in Mg alloys. ABSTRACT Data‐driven methods are emerging as

Synchrotron x-ray measurement and finite element analysis of residual strain in TIG welded aluminium alloy 2024 [PDF]
Residual strains have been measured in a tungsten inert gas (TIG) butt-welded 2024 aluminum alloy plate using synchrotron X-ray diffraction. Novel two-dimensional strain maps spanning the entire plate reveal steep gradients in residual stress and provide

Solidification of Tungsten Inert Gas–Welded Austenitic Stainless Steel with 0.17 wt% N
The classical Scheil model with fast diffusion of nitrogen is used to describe the solidification of the weld seam from austenitic CrMnNi–N steel. The microsegregation of the elements Ni, Cr, Mn, Mo, and N is calculated and compared with experimental findings. Further, the correlation between secondary dendrite arm spacing and cooling rate is made.

Joining Optimization, Temperature, and IMC Evaluation for AL to Steel Friction Stir Spot Welding
Friction stir spot welding (FSSW) effectively solves many problematic welding metals, such as dissimilar metals and thin alloy sheets. Carbon steel‐AISI 1006 top sheet and an aluminum alloy AA2024‐T3 bottom sheet were joined by FSSW with a cylindrical pinless tool. Joints are evaluated in terms of temperature, mechanical characteristics, microstructure,
