Tailoring grain refinement through thickness in magnesium alloy via stationary shoulder friction stir processing and copper backing plate
TL;DR: In this article, stationary shoulder friction stir processing (SSFSP) with steel and copper backing plates was conducted to develop ultrafine grains (UFG) in 6.35mm thick magnesium alloy.

Through-thickness microstructure and mechanical properties in stationary shoulder friction stir processed AA7075
TL;DR: In this paper, a study of shoulder friction stir processing of high strength thick AA7075 aluminium alloy demonstrated tiny gradient in the microstructure refinement across the thickness, which was attributed to...

Strengthening mechanism of friction stir welded alpha titanium alloy specially designed T-joints
TL;DR: In this paper, the Ti-4Al-0.005B (TA5, Chinese brand) was used in a specially designed T-joint joined by friction stir welding, where two plates served as the skins and one plate served as stringer with two separate welds.

The sensitivity analysis of microstructure and mechanical properties to welding parameters for linear friction welded rail steel joints
TL;DR: In this article, high carbon rail steel (U71Mn, Chinese grade) was welded by linear friction welding (LFW) under different welding parameters, and the microstructure and mechanical properties of the joints were characterized to investigate the connection mechanism of the joint.

Effect of an improved pin design on weld formability and mechanical properties of adjustable-gap bobbin-tool friction stir welded Al-Cu aluminum alloy joints
TL;DR: In this paper, an improved tool was designed to enhance weld formation for adjustable-gap bobbin-tool friction stir welding, and the maximum density of geometrically necessary dislocations reached 2.52 × 10 13 m - 2 presenting at the stir zone (SZ).
