Research is ongoing at Stanford University on the catalytic decomposition of nitrous oxide as an environmentally friendly monopropellant for propulsion and power applications. Two meso-scale planar monopropellant thrusters have been successfully tested: one made of monolithic silicon carbide utilizing a commercially supplied catalyst, and the other made of Hastelloy-X ® utilizing a rhodium base...

WEDM is a one of the non-conventional machining processes used for machining complex shape components and hard materials to produce intricate shapes on the wide variety of materials. With the increasing demands of high surface finish and high rate of MRR of complex shape geometries, WEDM machining process is now being replaced by non-traditional machining processes. According to this paper, opt...

In polycrystalline metals, local deformation heterogeneities induced by the microstructure influence fatigue crack initiation and micro-crack propagation. The localization in plastic strains associated with heterogeneous deformation has been described as a necessary condition and a precursor for the nucleation of fatigue cracks. However, a clear and quantitative assessment of the correlation be...
