Weld zone simulation and ballistic testing were employed to determine the effect of friction stir welding on the ballistic performance in the HAZ, thermomechanically affected zone and nugget, under direct impact, of AA 7010-T7651 high-strength alumi…

In the realm of armor steels, the relationship between hardness and ballistic performance is crucial. Different hardness levels can lead to various modes of failure upon ballistic impact. However, when armor-grade steel plates undergo welding, the b…

Welding trials are reported to demonstrate joint formation between S45C mild steel and aluminium alloy 6063 using a friction stir diffusion process. Welding experiments were undertaken using a machining centre with a cemented carbide rotating tool, …

Microstructural and textural variations in friction stir weld-affected regions of near-alpha Ti-5111 alloys (Ti, 5%Al, 1%Sn, 1%Zr, 1%V, 0.8%Mo) were investigated experimentally and a model incorporating micro-shear banding was proposed to account fo…

Corner "Friction Stir Welding" technology is beneficial for T-joints in a variety of products, including aluminum aircraft. Although a stationary shoulder device and Corner Stationary Shoulder FSW (CSS-FSW) are promising technology to realize T-join…

Friction stir welding (FSW) has been widely used in the automotive, aerospace, and high-tech industries due to its superior mechanical properties after welding. However, when it becomes matter to perform a high-quality joint using FSW, it is necessa…

Butt welding experiments were undertaken to investigate the feasibility of joining a metal matrix composite (MMC), comprising an Al-10%Si matrix and 20 vol.% SiC particles, to an AA-6063-T5 alloy by friction stir welding (FSW). Optimum process param…
