Taguchi Approach for Optimization of Parameters that Effect Grain Size of Cast A357 Alloy
Archives of Foundry Engineering, 2017 Grain refining and modification are common foundry practice for improving properties of cast Al-Si alloys. In general, these types of treatments provide better fluidity, decreased porosity, higher yield strength and ductility. However, in practice, there

Grain refinement of AZ31 magnesium alloy by electromagnetic stirring under effect of grain-refiner
Bulletin of Materials Science, 2012 The effects of electromagnetic stirring and Al4C3 grain refiner on the grain refinement of semi-continuously cast AZ31 magnesium alloy were discussed in this investigation. The results indicate that electromagnetic stirring has an effective refining effect on the grain size of AZ31 magnesium alloy under the effect of Al4C3 grain refiner ...

New grain refinement method for aluminum cast alloys without adding grain refiner.
Journal of Advanced Science, 2001 Grain refiner has conventionally been added during the casting process of grain refinement, but it has recently become a recycling problem, which calls for the efforts for development of a new grain refinement method. In this paper, a technological breakthrough has been achieved, where grain refinement was successfully completed by applying ultrasonic ...

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.
