In this study, SiCp particles were reinforced at volumetric ratios of 5%, 10%, 15% and 20% into the EN AW 5756 (AlMg3) metal matrix composite by using squeeze casting method. The squeezing process was carried out for 10 seconds under a pressure 80 MPa. changes in wear behaviors friction coefficients 5754/SiCp samples examined under1.0 N force, 5000 cycles with 0.04 m/s sliding speed. As result ...

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...

Scanning microscopes will be vital elements in the atom engineer's toolbox, and our understanding of their operation continues to advance rapidly. We can look forward to finding a sound basis not only for imaging and spectroscopy of single atoms, but also their manipulation and the creation of wholly novel nanostructures. (residues 35–139) binds to SicP in an extended , non-globular conformatio...

In order to evaluate the uniform of SiCp reinforced aluminum metal-matrix composites (MMC) fabricated by powder metallurgy, the ultrasonic velocity imaging was carried out with the method of thickness independent reflector plate (TIRP). Ultrasonic velocity in MMC can be used to calculate the stiffness constants and Yang’s modulus, which are influenced by the volume percentage of SiCp. The TIRP ...

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. Three factor three lev...

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 Italian Society of Pediatric Surgery (SICP) together with The Italian Society of Pediatric Anesthesia (SARNePI) through a systematic analysis of the scientific literature, followed by a consensus conference held in Perugia on 2015, have produced some evidence based guidelines on the feasibility of day surgery in relation to different pediatric surgical procedures. The main aspects of the pr...

By hot extrusion at 250°C and electrical pulse treatment (EPT) of 40 ?s duration 10 min processing time, a homogeneous matrix microstructure with an average grain size 0.91 ?m abundant Mg17Al12 phase was obtained in SiCp/AZ91 magnesium composite. Moreover, SiCp were helpful to promote the accumulation crystal defects precipitation phase. After 250°C, yield strength (YS) ultimate tensile (UTS) c...

The Steady state creep behaviour of a functionally graded cylinder made of isotropic composite containing varying distribution of silicon carbide particles has been investigated by a mathematical model. The creep behaviour of the FGM is described by a Norton's Power law. The effect of varying distribution of SiCP particles of creep stresses and creep rates in the FGM cylinder has been anal...
