In this work, nickel aluminum bronze (NAB)/Zn composites were prepared by friction stir processing (FSP), and the selective phase/area corrosion behavior of was studied in micro/nano-scale SEM FIB/TEM. The results show that excessive Zn element can accelerate or cause serious β′ phase corrosion. areas with high content, rich CuZn particles κ boundaries, are also locations for priority

Friction stir processing was applied for fabricating an aluminum alloy based hybrid nano composite reinforced with nano sized Al2O3 and micro sized graphite particles. A mixture of Al2O3 and graphite particles was packed into a groove with 1 mm width and 4.5 mm depth, which had been cut in 5083 aluminum plate of 10 mm thick. Packed groove was subjected to friction stir processing in order to im...

Friction stir welding and processing (FSW/FSP) involves severe plastic deformation of metals or polymers at high temperature around a rotating tool. The material’s flow is usually modelled by FEM using complex combination thermomechanical friction models. However, the description behavior first atomic layers in contact with tool cannot be undertaken continuum mechanics modelling such as FEM. Am...

Friction stir processing (FSP) is a novel method of metal surface modification during the process by addition strengthening particles. FSP produced refined microstructures with development added ceramic particles on metal. In this FSP, mechanical characteristics were enhanced parameters, tool spinning speed, traverse speed and axial force high carbon chromium die steel (non-consumable tool). re...

Abstract The strength and wear resistance of aluminium alloys must be improved to enhance their usage in lightweight constructions. Thus, this study, graphene nanoplates (GNPs) boron nitride (BN) nanoparticles were reinforced into the Al 5251 alloy by friction stir processing (FSP). aluminum sheets patterned with holes filled mono GNPs, BN a hybrid GNPs. microstructure, wear, mechanical propert...

Friction stir processing (FSP) was used to modify the microstructure and improve mechanical properties corrosion resistance of an Mg–Al–Ca alloy. The results demonstrated that, after FSP, grain size alloy decreased from 13.3 6.7 μm. Meanwhile, Al8Mn5 phase broken dispersed, its amount increased. yield strength ultimate tensile were increased by 17.0% 10.1%, respectively, due combination fine gr...

Friction stir processing (FSP) was conducted on a SAF 2205 duplex stainless steel at advancing speed of 50 mm/min and rotational speed of 400 rpm.  Characterization of evolved material was studied using electron microscopy equipped with electron back scattered diffraction (EBSD) system. The results indicated that the severe plastic deformation and the heat generated during the FSP developed a v...

Abstract The focus of this study is to see if Friction Stir Processing can improve the properties an aluminium alloy with Boron Nitride (BN) particles on surface. (FSP) a new surface alteration technique that uses friction cause plastic deformation, resulting in grain refining and improved mechanical properties. To process 2024 plates, straight cylinder tool was used under varying parameters co...

Magnesium (Mg) and its alloys have attached more attention because of their potential as a new type biodegradable metal materials. In this work, AZ31/ZrO 2 nanocomposites with good uniformity were prepared successfully by friction stir processing (FSP). The scanning electron microscope (SEM) transmission (TEM) used to characterize the microstructure composites. mechanical properties, electroche...
