Current State of Semi-Solid Net-Shape Die Casting

Process modeling of microalloyed steel for near net shape casting

Strip casting is an emerging technology for flat products; it is based on the concept of near-net shape casting; it holds potential for substantial energy saving and reduction in environmentally undesirable emission. In conventional thermo-mechanical processing, the pinning pressure due to the effects of Nb and NbC on boundary mobility is used to advantage to retard static recrystallisation and...

Optimization of Microstructure and Mechanical Properties of Al-A360 Produced by Semi-Solid Casting

Semi-Solid Casting (SSM) is a new process that could produce globular structures with mechanical properties. The cooling slope method (CLM) is a one of this process that was employed to produce the A360 feedstock. In this method, The dendritic primary phase in the conventionally cast A356 alloy has transformed into a non-dendritic one. In this paper, The molten alloy with the temperature (PT) o...

Casting the autophagy net

C ells can degrade cytoplasmic components by capturing them inside a double-membraned vesicle called the autophagosome that then delivers them to lysosomes to be broken down and recycled. This process, known as autophagy, occurs at basal levels in all cells, and is upregulated in response to starvation or other stresses as a cell survival mechanism. But autophagy is a double-edged sword that ca...

A Solid State Current Limiter

Abstract Utility engineers faced with the challenges of integrating new generation into existing power systems, clearing faults more quickly or finding an alternative to SF6 breakers will soon have a new product to meet all of their needs: a solid state current limiting circuit breaker. Electric utilities have long wished for a practical, reasonably priced, solid state circuit breaker which cou...
