The current work seeks to discover and choose the proper friction stir processing (FSP) settings for aluminum alloy 7075 surface composites enhanced by adding three unique nanoparticles of titanium dioxide (TiO2), B4C, graphene superior performance. FSP is only method that produces higher amounts particle distribution nanoscale reinforcing. For sample fabrication, a special relatively high rota...

This work studies the effect of incorporating a mix reinforcement particles hard and soft nature on microstructure mechanical physical properties high-strength aluminum alloy, AA7075. A friction stir processing technique was used for compositing surface this alloy. The vanadium carbide (VC) selected to be reinforcement, while boron nitride (BN) graphene nanoplates (GNPs) were chosen as reinforc...

We analyze the role of different rivet and die design parameters on feasibility quality self-piercing riveting (SPR) joining metallic sheet stacks. In particular, a similar aluminum-to?aluminum stack (AA2019/AA7075-F) dissimilar aluminum-to-steel (AA7075-F/BA0270) is investigated, both experimentally numerically. Towards this, materials are characterized to obtain their elastoplastic fracture a...

in this paper, welding feasibility between aa1100, aa5050 and aa6082 aluminum alloys and a441 aisi steel by friction stir welding has been studied. mathematical analysis of the heat generation during process showed that the maximum temperature produced in aa6082 aluminum alloy and a441 aisi joint but heat distribution in aa1100 aluminum alloy was higher than the other alloys. the investigation ...

The success of the thixoforming process depends on the possibility to confer to material, when it is found in the semisolid state, a microstructure characterized by globular particles of solid phase surrounded by a continuous film of liquid phase; such microstructure is obtainable through particular thermo-mechanical treatments. In the present research, in order to optimize the influence of pro...

AA7075 aluminum alloy is widely used for several high-technology applications its high mechanical strength to weight ratio but still the subject of studies seeking a further increase in properties. A commercial powder used, either as-received or after ball-milling. Dense samples are prepared one step by Spark Plasma Sintering, at 550 °C with holding time 15 min and uniaxial pressure 100 MPa. No...

New generations of high strength aluminum alloys are increasingly used in automotive industry. AA7075 is one the strongest industrial use today. The outstanding properties open possibility to this alloy industry as a possible alternative material for car body elements instead steels. Growing demand led development new technologies, processes. Solution heat treatment, forming, and in-die quenchi...
