In the present paper, fracture mechanisms and corresponding stress distributions in aluminium cast alloy locally reinforced by SiC particles and Al2O3 whiskers under monotonic and cyclic load are investigated experimentally and numerically. The material is monotonically and cyclically deformed to failure at room temperature. The fracture origin and the fracture path are investigated on the frac...

In the preparation process of composites, implementation green manufacturing technology has an important impact on improving material properties and efficiency. The adopting not only greatly reduces energy consumption but also effectively avoids environmental pollution. Compared with traditional process, for is a new concept idea. Microwave sintering such efficient, clean, pollution-free so it ...

Diamond-SiC composites are attractive for improving the catastrophic fracture behaviour of SiC. However, fundamental knowledge is missing about structure this system and mechanism diamond graphitization. We used spark plasma sintering to study diamond-Si-SiC between 1600 2000?C in function nanocrystalline (ND) microcrystalline (MD) addition as well quantity Sibonding phase. Increasing temperatu...

Lightweight corundum-mullite thermal insulation materials were successfully prepared by microwave sintering at low temperature. The effects of temperatures, PMMA microspheres and SiC particles on structure properties as-prepared investigated. became a hot spot under the action field, these local high temperature areas promoted formation growth mullite whiskers. burn out, leaving pores which cou...

Abstract: SiC nano particles with mono dispersed distribution were synthesized by using of silicon alkoxides and phenolic resin as starting materials. After synthesis of sample, characterizations of the obtained powder were investigated via Fourier Transform Infrared Spectroscopy (FTIR) with 400-4000 cm-1, X-ray Diffractometry (XRD), Laser Particle Size Analyzing (LPSA), Si29 NMR analysis, Scan...

After the pioneering investigations into graphene-based electronics at Georgia Tech, great strides have been made developing epitaxial graphene on silicon carbide (EG) as a new electronic material. EG has not only demonstrated its potential for large scale applications, it also has become an important material for fundamental two-dimensional electron gas physics. It was long known that graphene...

The nano-sized particle-reinforced metal matrix composites are the new potential material which could be applied in many industry fields, possess superior strength, ductility, and wear resistance comparison with micro-sized composites. However, fabrication methods of nanoparticles complex expensive. In present research, micron size SiC particles milled for 45-hours wet milling arrangement a pla...
