Investigators from Amirkabir University of Technology Report New Data on Metallurgy (Optimizing Powder Distribution in Production of Surface Nano-Composite via Friction Stir Processing)

By a News Reporter-Staff News Editor at Journal of Technology -- Researchers detail new data in Metallurgy. According to news reporting out of Tehran, Iran, by VerticalNews editors, research stated, "Notwithstanding the extensive interest in using friction stir processing (FSP) for producing metal matrix composite (MMC), more uniform powder distribution along the composite zone is still needed. In most studies, one groove is machined out of the specimen, filled with powder, and then processed by identical passes."

Our news journalists obtained a quote from the research from the Amirkabir University of Technology, "In this investigation, an innovative technique was used that involved machining out of three gradient grooves with increasing depth from the advancing side to the retreating side instead of using a conventional sample with just a groove. Macro, optical, and scanning electron microscopy (SEM) images and microhardness test were used to evaluate the powder distribution. The images indicated that the most uniform distribution of SiC particles in the whole composite zone was related to a three-gradient grooves sample."

According to the news editors, the research concluded: "Microohardness measurement of a three-gradient grooves sample, carried out along the cross section and perpendicular to the traverse direction of FSP, experiences less fluctuation in hardness compared with other techniques."
