TL;DR: In this article, a study of diffusion wear mechanism in 1.2344 X40CrMoV5-1 steel FSW tool has been carried out from the standpoint of tribological layer generation and interaction with the tool's metal.

TL;DR: In this article, high-temperature sliding experiments have been carried out to study both direct and back adhesion transfer between Al-Mg alloy metal and the ball bearing steel sample, and it was shown that a transfer layer consisting of aluminum alloy formed on the trailing hemisphere of the steel ball and then could stick back to the wear groove surface of the disk.

TL;DR: In this paper, the authors used an electron beam wire-feed additive manufacturing to obtain different amounts of vermicular δ-ferrite that depended on the heat input value used.

TL;DR: In this paper, the effect of ultrasonic energy on the microstructural evolution of the welded metal was investigated and it was found that ultrasonic-assisted friction stir welding (UAFSW) reduced the recrystallized grain size in the stirring zone (SZ), facilitated strain-induced dissolution of both soluble and insoluble intermetallic precipitates, and enhanced solid solution grain recratherization and precipitation of coherent metastable phases.

TL;DR: In this paper, the results of an investigation into a microstructure formation on a wire-feed electron beam additive manufactured "steel-copper" bimetallic sample were revealed.
