Producing items that are of both high quality and long lasting is a difficult task for companies right now. There huge need wide range engineering materials in today’s technologically advanced globe. The strength qualities the material determine amount may be used. Due to its excellent mechanical low density, aluminum-7075 alloy mostly employed transportation applications such as aerospace, mar...

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...

Abstract Aluminium alloy (Al7075) based hybrid metal matrix composites reinforced with Silicon carbide (SiC) and Tungsten (WC), at 5 wt% each are considered for this investigation, which developed by stir casting methodology. Material characteristic analysis both micro macro (Tensile strength hardness) level were performed. This investigation is further progressed drilling of the using titanium...

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 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...

We present a case study where we use automated formal analysis to reason about problem-frame concerns. The descriptions of the problem domains, machine and requirements are written in the Alloy language. We show that an evaluation of results and counterexamples provided by a model finder can reveal useful information that can help remove inconsistencies as well as composition errors.
