An innovative friction stir processing variant, named Upward Friction Stir Processing (UFSP), for producing customized materials with multifunctional particles is presented. In the UFSP, an upward ...

In order to obtain high-quality aluminum foam components, a new preparation method for 7075 closed-cell based on friction stir processing (FSP) was proposed. The influence of process parameters microstructures Al precursor investigated by optical metallographic microscope and scanning electronic (OM/SEM). temperature field flow the during FSP were simulated Fluent CFD software. formability anal...

Superplasticity denotes the ability of a limited number materials to achieve exceptionally high tensile elongations at least 400%. Experiments show that Al-Mg-Sc alloys provide excellent capabilities for achieving superplastic flow and also they can be formed easily in biaxial forming operations. It is important, therefore, examine mechanism when alloy prepared using different procedures. This ...

the friction stir process (fsp) is a solid state process, which has been used to insert reinforcing particles into the structure of a material to create a composite with improved properties. magnesium is a light structural metal that is increasingly used in the aerospace and automobile industries. in this research, sic nanoparticles were added to az31 alloy using fsp in two overlaps of 100% and...

Friction stir welding is a relatively new solid-state joining technique which is widely adopted in different industry fields to join different metallic alloys that are hard to weld by conventional fusion welding. Friction stir welding is a highly complex process comprising several highly coupled physical phenomena. The complex geometry of some kinds of joints and their three dimensional nature ...

In this research, surface composite layers containing nano sized TiB2, Al2O3-TiB2, ZrO2 and CNT particles have been fabricated on Aluminum alloy substrates by friction stir processing. The effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nano...

A thermo-mechanical model of friction stir processing (FSP) using the Altair based on meshless Smoothed-Particle Hydrodynamics (SPH) was developed and verified experimentally. Process parameters adopted for both experimentation simulation during FSP AZ91 were 1000 rpm tool stirring speed, 40 mm/min advancing 0° tilt angle. The numerical analysis predicted temperature distribution material movem...

In the present study, various literature based on high strain rate behaviour of ultrafine-grained (UFG) aluminium alloys produced through severe plastic deformation techniques have been discussed. It was observed from that under (3000–120000 s−1) adiabatic shear bands (ASBs) were formed which is main reason for dynamic failure. These ASBs failure Al when they exposed to impact. The are mainly t...
