Fracture mechanisms of aluminium cast alloy locally reinforced by SiC particles and Al_2O_3 whiskers under monotonic and cyclic load
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...
متن کاملThe Role of Nano Sic Whiskers on the Strength and Density of Aluminum Silicate-SiC-C Compounds as a Reinforced Steel Refractory
This study describes the role of in situ nano SiC whiskers on the strength and density of alumina silicate–SiC-carbonrefractory compounds. The prepared specimens were composed of 65 wt. % chamotte as alumina silicatecompound, 15 wt. % SiC-containing material regenerates and 10 wt. % fine coke and 10 wt. % liquid resole asbinder. Different values of additives (such as silicon a...
متن کاملAnisotropic etching of SiC whiskers.
We have demonstrated a method of producing nanoplatelets or complex well-ordered nanostructures from silicon carbide (SiC) whiskers. Preferential etching of SiC whiskers in a mixture of hydrofluoric and nitric acids (3:1 ratio) at 100 degrees C results in the selective removal of cubic SiC and the formation of complex structures resembling a pagoda architecture. Possible mechanisms governing se...
متن کاملReinforcement architectures and thermal fatigue in diamond particle-reinforced aluminum
Aluminum reinforced by 60 vol.% diamond particles has been investigated as a potential heat sink material for high power electronics. Diamond (CD) is used as reinforcement contributing its high thermal conductivity (TC 1000 W mK ) and low coefficient thermal expansion (CTE 1 ppm K ). An Al matrix enables shaping and joining of the composite components. Interface bonding is improved by limited c...
متن کاملEFFECT OF T6 HEAT TREATMENT ON MECHANICAL PROPERTIES OF CERAMIC REINFORCED CASTED ALUMINUM ALLOY
Aluminium base alloy (Al-Cu-Si) was reinforced with silicon carbide (SiC) particles, in various percentage compositions from 0-20 wt%. Silicon carbide particle size of 20µm was selected. The molten slurry of SiC reinforced base aluminium metal was casted through green and dry sand casting methods and solidification process was carried out under ambient conditions. A selected population...
