Because of their excellent high temperature characteristics, Ni-based single-crystal alloys are used in applications where operating temperatures exceed 900ºC. The initiation of cracks under these conditions is generally associated with micro-scale porosities (typically between 10 and 20 microns). A rate-dependent crystallographic constitutive model in conjunction with a mass diffusion model has been used to study crack initiation in single crystal nickel-base superalloys, exposed to an oxidizing environment and subjected to ....etc

HIGH TEMPERATURE SUPER CONDUCTORS

ABSTRACT :

A substantial fraction of electricity is lost in the form of heat through resistance associated with the traditional conductors such as copper or aluminum. More than 15% of the world's generated electricity is los ....etc

SUPERCONDUCTIVITY is the ability of certain materials to conduct electric current with no resistance and extremely low losses. This ability to carry large amounts of currents can be applied to electric power devices such as motors and generators and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the electricity ordinary copper or aluminium wires of same size.Scientists had been intrigued with the concept of superconductivity since its discovery in the early 1900?s, but the extreme low tem ....etc
