Improved baseplate materials are required to provide superior reliability and heat transfer as IGBT power density increases. The key is for the baseplate thermal coefficient of expansion (TCE) to be matched to the module design and to have sufficient thermal conductivity (κ). Aluminum Silicon Carbide (AlSiC), a metal matrix composite material, provides a TCE that is compatible with the attachme...

Abstract Creep response for isotropic axisymmetric rotating disc made of a particle-reinforced FGM has been investigated in the present study. The result obtained for non linear variation of particle distribution along the radial distance of the disc are compared with that of discs containing the same amount of particle distributed uniformly or linearly along the radial distance. The disc under...

Creep behavior of thick-walled functionally graded cylinder consisting of AlSiC and subjected to internal pressure and high temperature has been analyzed. The functional relationship between strain rate with stress can be described by the well known threshold stress based creep law with a stress exponent of five. The effect of imposing non-linear particle gradient on the distribution of creep s...
