Friction stir processing (FSP) was used as a cladding method for the fabrication of a AA2024 clad layer on a AA1050 sheet. Crossover multi pass FSP with 50% overlap was considered as the cladding method. Effects of the number of FSP passes and post heat treatment on the microstructure and properties of clad layers were evaluated. Microstructural evolutions during the FSP and heat treatment were...

Abstract. In this study the Al-4.8Mg-1.0Mn-0.15Cr alloy was frictionally stir processed in order to enhance grain refinement effect and superplastic properties. The microstructure after friction processing (FSP) analyzed using light, scanning transmission electron microscopies. An additional cold rolling (50%) performed FSP, a comparative terms of superplasticity done between samples hot furthe...

A composite material based on the WE43 magnesium alloy and containing nano-sized hardystonite ceramic particles was processed by means of friction stir processing (FSP). Compressive strength strain-at-failure increased as a combined result FSP nanoparticle reinforcement. The results potentiondynamic polarization electrochemical impedance spectroscopy tests indicated that corrosion mechanism nan...

Ultra-fine grained (UFG) structure (~0.6 µm) was produced in the stir zone (SZ) of 6061-T6 aluminum alloy joints using friction stir processing (FSP) cooled by liquid nitrogen (N2). A new experimental set-up was used to simultaneously quench the lower and upper surfaces of the samples during the processing. In addition, FSPed joints, using a steel backing plate, were produced at room temperatur...

In this work, a fine-grained structure with a uniform distribution of TiB2 particles and precipitates was achieved in TiB2 particle-reinforced (PR) Al-Zn-Mg-Cu alloys by friction stir processing (FSP). The effects of multi-pass FSP on the microstructure, and TiB2 particle distribution, as well as the microstructural evolution in the following T6 treatment, were investigated by X-ray diffraction...

Herein, Compact-Testing (CT ) and Charpy V-Notch (CVN) testing have been done on four Friction-Stir-Processed (FSPed) samples: BM (Base-Metal), FS (FSPed-Sample), FN5 (FSP Nano-ZrO2-coated/560 rpm rotational speed) and FN9 (FSP Nano-ZrO2-coated/900 rpm), to investigate the KIC and the dominant parameters on it for St 37 steel. Experiments are also surveyed and validated by ABAQUS. Results showe...

Abstract Aluminum alloy AA1100 has less wear resistance and mechanical properties than that of other aluminum alloys. This research work is on the fabrication surface composites by friction stir processing (FSP). The are fabricated reinforcing hBN (hexagonal Boron Nitride) in to improve tribological properties. influence process parameters, rotational speed (rpm), transverse (mm/min) microstruc...

The beneficial effect of the friction stir processing (FSP) technique for improving properties fabricated additive parts through microstructural refinement and repairing metallurgical defects has shown its ability to be integrated into a hybrid manufacturing system. In present work, conventional GMAW TIG-based processes were further post-processed with process (FSP). case + processed beads, imp...

Abstract The present endeavour is to augment mechanical attributes via friction stir processing (FSP) in hypereutectic aluminium–silicon castings by the means of microstructural modifications and defects reduction. Wherein, study proceeds with mainly two approaches namely, alteration tool revolution (TR) number FSP passes. prepared specimens were evaluated investigating volume fraction porositi...
