Aerospace applications and energy-saving strategies in general raised the interest and study in the field of lightweight materials, especially on aluminum alloys. Aluminum alloy itself does not have appropriate wear resistance. Therefore, improvement of surface properties is required in practical applications, especially when aluminum is in contact with other parts. In this work, first titanium...

In this study, metal matrix hybrid composites obtained by adding B4C and graphene nanoplatelets (GNPs) powders as reinforcement elements to Al7075 were produced powder metallurgy (P/M) method. Mixture prepared supplementing with different weight ratios of (2-5-10%) GNPs (0.5%) are compressed at room temperature pressing pressures (600-700-800 MPa) then temperatures (500-550- 600C) was sintered...

Shot peening technologies can improve the performance of materials and extend service life parts. Cavitation water jet (CWJP) is a new shot technology that uses shear effect high-speed in submerged environment to produce cluster bubbles, thereby achieving significant increase impact performance. In this paper, CWJP was used strengthen surface 7075 aluminum alloy (Al7075), effects with different...

The current study focuses on the properties of dry sliding characteristics and impact strength two different aluminum alloys that were reinforced with 100 nm sized Silicon carbide (SiC) Aluminum oxide (Al2O3) ceramic particles, for improving mechanical final alloy mixing materials characteristics. Stir casting method is adopted fabricating composites, matrix being Al6061 Al7075, utilizing three...

Drilling two different materials in a layer, or stack-up, is being practiced widely the aerospace industry to minimize critical dimension mismatch and error subsequent assembly process, but compatibility of drill compensate differing properties composite still major challenge industry. In this paper, effect customized twist geometry drilling parameters are investigated based on thrust force sig...

In this study, mechanically milled (MM) Al-24TiO2-20B2O3 powder in molten Al7075 matrix was used order to fabricate in-situ TiB2 and Al2O3 reinforcements matrix. Differential thermal analysis (DTA) examination adopted find reaction temperature between Al, TiO2, B2O3 powders. X-Ray Diffraction (XRD) patterns showed the existence of peaks (750 °C at Ar atmosphere) MM powder. Scanning Electron Mic...

In the present research, effects of volume fraction SiC+Al2O3 particles and aging temperature on machinability stir-casted Al7075 metal matrix composites (MMC) have been investigated. The hybrid were fabricated using liquid metallurgy route. was reinforced with different wt. % SiC (3%, 6%, 9%) Al2O3 (2%, 4%, 6%) which used to fabricate composites. samples aged at temperatures (140 ºC, 160 180 º...
