Studies on Multi-pass Friction Stir Processing (FSP) of Fe49.5Mn30Co10Cr10C0.5, a metastable dual-phase High Entropy Alloy (HEA), were carried out with the aim to systematically investigate microstructural changes occurring during different passes, and evaluate mechanical response this alloy progressive passes. A reduction in grain size change HCP volume fraction was observed after each pass. D...

In this study, post-weld friction stir processing (FSP) was applied to eliminate the grain coarsening disadvantages encountered in heat-affected zone when joining AA5754 aluminum alloy with Gas Tungsten Arc Welding (GTAW). As a result of welding two passes and low heat input by selecting appropriate parameters, all seams were produced without macro defects. Despite these precautions, has occurr...

The influence of the pre-implanted reinforced particles on temperature field and flow processed zone directly determines microstructure properties aluminum matrix composites fabricated by friction stir processing (FSP). However, differences in characteristics materials, especially effect plastic have rarely been reported. In this study, distribution was obtained experimental measurement numeric...

The present study has expounded the effect of high temperatures on tensile deformation AZ31 magnesium alloy processed through a single-pass friction stir processing (FSP). major operation parameters, namely rotation speed and traverse FSP tool, were varied which led to extensive dynamic recrystallization (DRX) in zone (SZ) engendering maximum grain refinement about 63% as compared base metal. l...

Friction stir processing (FSP) offers a unique opportunity to tailor the microstructure and improve mechanical properties due combination of extensive strains, high temperatures, high-strain rates inherent process. Reactive friction was carried out in order produce situ Al/(Al13Fe4 + Al2O3) hybrid nanocomposites on wrought/as-annealed (673 K) AA1050 substrate. The active mixture pre-ball milled...

(57) ABSTRACT Metallic materials may be joined utilizing a friction stir processing teclmique. The friction stir processing technique utilizes a shaped, rotating tool to move material from one side of the joint to be welded to the other without liquefying the base material.

A commercial 2024 aluminum alloy was heat treated at 280 °C for 48 h and then slow cooled in a furnace to obtain minimum hardness. This material friction stir processed (FSP) using three sets of processing conditions. To study the effect on microstructure high temperature mechanical properties, materials were tested tension an initial strain rate 10−2 s−1 range 200 450 °C. Processing severity s...

The aims of this study were to fabricate a novel titanium/silicon carbide (Ti/SiC) metal matrix nanocomposite (MMNC) by friction stir processing (FSP) and to investigate its microstructure and mechanical properties. In addition, the adhesion, proliferation and osteogenic differentiation of rat bone marrow stromal cells (BMSCs) on the nanocomposite surface were investigated. The MMNC microstruct...
