SiC-reinforced aluminum matrix composites (SiCp/Al composites) are typically difficult-to-machine material, and the irregular SiC diffused in SiCp/Al make surface quality worse. In this paper, a single-point cutting simulation with variable plane depth were conducted for composite higher volume fraction (65 Vol%) alloy. The morphology characteristics of composites, which mainly include breaking...

The effect of deep cryogenic treatment (DCT) on the artificial ageing kinetics a SiC particles reinforced aluminum alloy composite (SiCp-Al) is experimentally studied in this paper. evolutions both macro-properties (i.e., yield strength and ultimate tensile strength) microstructures (precipitates) have been investigated by set hardness tests, microstructural observations (scanning electron micr...

The SiC particles (SiCp, mass fraction 30 %) reinforced with the Al-Si-Cu-Mg matrix composite have been prepared using one-way press method, sintering, and hot extrusion. The composite was subjected to solid solution treatment at temperatures of 470 °C, 485 °C, 500 °C, 515 °C, and 530 °C for 4 h. The sample was then subjected to ageing treatment at temperatures of 160 °C and 180 °C during diffe...

Revealing the interactions of sound waves with both SiC particles and internal defects is crucial for facilitating detectability defect features in SiCp/Al by using ultrasonic testing (UT). In present work, we demonstrate feasibility UT flat-bottom holes diameters ranging from 0.2 mm to 2 composites through combination finite element (FE) simulations experiments. Specially, a 2D FE model consis...

Metal matrix composite (MMC) technology can improve the service performance of matrix metals and alloys. Most magnesium alloy based MMCs are produced via a casting process, therefore the casting microstructures are of vital importance to their performance in service. The formation of microstructure during solidification of MMCs is mainly influenced by four factors: nucleation (or its absence) o...

AZ91D and 8.5vol.% SiCp/AZ91D magnesium matrix composites were fabricated by a semi-solid extruded processing method, treated with solution aging heat treatment. The effects of SiCp on the microstructures alloy during recrystallization studied observing analyzing microstructure evolution extrusions treatments. results show that addition inhibits dynamic extrusion only 26% volume fraction recrys...

Metal Matrix Composites (MMCs) are present engineering materials which have more advantages when compare to conventional materials. Magnesium based MMCs among the MMCs have become an important research subject because of their low density and high strength/weight ratio in recent years. The aim of this study is to find out the most influence factors of the electro-discharge machining (EDM) proce...

A dense Al-SiCp nanocomposite coating with high volume fraction of nano SiCp reinforcement (60 vol.%) was fabricated through cold spraying deposition milled Al-60SiCp powder in the present paper. Microstructure evolution during ball milling process, microstructure characteristics and hardness sprayed were studied. Al particles underwent fracture deformation SiC evenly distributed soft base mate...

The aim of this investigation is to optimize the process parameters obtain minimum corrosion rate and weight loss Al/SiCp metal matrix composites. A Taguchi based grey relation analysis was carried out. such as number hours dipped in 3% NaCl solution, vol.% SiCp aging at 170°C for were considered. working range each fixed on low rate. test out using relationship analysis.
