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...

Metal Matrix Composites is two or more combination material with aluminum metal as matrix and devolved to fix act, strength, high temperature stability hardness. composites have been developed so many because it has low density, corrosion proof, cheap easy fabrication. Powder metallurgy technique one of fabrication process in solid state that still economic, doesn't need difficult equipment. Al...

Strains of the various Salmonella enterica serovars cause gastroenteritis or typhoid fever in humans, with virulence depending on the action of two type III secretion systems (Salmonella pathogenicity island 1 [SPI-1] and SPI-2). SptP is a Salmonella SPI-1 effector, involved in mediating recovery of the host cytoskeleton postinfection. SptP requires a chaperone, SicP, for stability and secretio...

A complete and detailed analysis of the microstructural development during ageing in an 8090 (Al-2.3Li-1.2Cu-1Mg-0.1Zr) alloy, an 8090/20wt%SiCp MMC, an Al-1.5Li-Cu-Mg MMC and an Al-Cu-Mg MMC (all with similar Cu and Mg contents) has been performed. Volume fractions of all precipitates relevant for precipitation strengthening of the alloys (δ' phase, S' phase and GPB zones) have been determined...

SiCp/Al composites are difficult-to-cut materials. In recent years, electrical arc discharge machining has been developed to improve the machinability of these However, there is a big challenge build satisfactory heat transfer model in machining. This not only because material property difference between reinforcement and matrix but also micro-dimension SiC reinforcements. paper established new...
