It is important to join materials for systems that require high-performance and minimize the defects may occur during this joining. Welding most common way joining but lightweight similar/ dissimilar materials, Friction Stir preferable its properties. Lightweight durable such as aluminum alloys are widely used in sectors defense industry, aerospace automotive high-speed train manufacturing. Som...

This paper analyzes local lattice rotations introduced in severely deformed polycrystalline titanium by friction stir welding. Nondestructive three-dimensional (3D) spatially resolved polychromatic X-ray microdiffraction, is used to resolve the local crystal structure of the restructured surface from neighboring local structures in the sample material. The measurements reveal strong gradients o...

Abrasion easily occurs due to the characteristic of usage environment such as oil sands and construction equipment, demand for a steel with excellent wear resistance is increasing in various industries where specific parts are frequently replaced. Recently, by controlling amount manganese, high manganese austenite steels improved low temperature brittleness performance have been developed widel...

The effect of the microstructure heterogeneity on the tensile plastic deformation characteristic of friction-stir-welded (FSW) dual-phase (DP) steel was investigated for the potential applications on the lightweight design of vehicles. Friction-stir-welded specimens with a butt joint configuration were prepared, and quasi-static tensile tests were conducted, to evaluate the tensile properties o...

Friction stir spot welding (FSSW) is a relatively new process that may have significant advantages compared to the fusion processes as follows joining of conventionally non-fusion weldable alloys, reduced distortion and improved mechanical properties alloys joints due pure solidstate metals. In this paper, three-dimensional model based on finite element analysis used study thermal history in sp...
