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...

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...

A357-SiCp/A357 layered composites were prepared using a semi-solid vacuum stirring suction casting method. The microstructures, mechanical properties, and thermal conductivities of the fabricated under different processes compared. Additionally, microstructural evolution characteristics performance enhancement mechanism discussed. results demonstrate that at 610 °C with low solid phase ratio ca...

In this paper, the SiCp/Al composites were bonded via laser-induced exothermic reactions of a Ni–Al–Zr interlayer. The interlayer was designed based on its property and chemical compatibility with composites. influences composition bonding pressure joint microstructure shear strength investigated. Results indicated that high occurred in realized reliable products eutectic structure NiAl+Ni2AlZr...

The effects of applied load, sliding speed and sliding distance on the dry sliding wear behavior of aged Al-SiCp-Gr composites were investigated. The specimen were fabricated by stir-casting technique. The pin-on-disc wear testing machine was used to investigate the wear rate by design of experiments based on L27 using Taguchi technique. Sliding distance was the most important variable that inf...

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...
