The PULSAR-II pulsed tokamak power plant design utilizes a blanket made of the vanadium alloy, V-5Cr-5Ti, and cooled with liquid lithium. The shield is made of a mixture of the low activation austenitic steel (Tenelon) and vanadium. The blanket is assumed to be replaced every 5.6 full power years (FPY) and the shield is assumed to stay in place for 30 FPY. The activity induced in the blanket at...

Industries largely rely on empirical tests to determine what composition and amount of TiBAl grain refiners add during the casting aluminum alloy for cast structure refinement. are master alloys having intermetallic particles within matrix, these mainly made Ti Al borides, higher melting point than matrix. Addition them melt, induces heterogeneous nucleation structures, which promotes solidific...

A new x-ray isothermal furnace has been developed, suitable for in situ observations of semi-solid processes including the transition from dendritic to globulitic grain morphology and coarsening metallic samples. homogeneous, temperature field is achieved using a novel heater concept. The structure sandwich-like with heating elements positioned beam line parallel sample. Planar heat transfer sa...

The production of high integrity thin-walled investment cast components can be achieved by controlling the solidification process. aim this work was to study effect grain refiner on aluminum alloy A356.0 plates produced casting using a controlled Moulds with plate thicknesses 0.7 mm, 1.5 mm and 2 were cast. melted in an electric resistance furnace, one mould process, second modified Strontium (...

The emerging switched-capacitor-based multilevel inverters offer interesting merits such as self-balancing of capacitor voltages and boosting voltage gain. While the switched capacitors (SCs) in these topologies are charged parallel with dc source, severe current spikes issue is inevitable, rendering them impractical at high power. This article proposes a novel T-type inverter that mitigates by...
