Cited by: 2062021-12-15 Stirring and vibration during solidification are widely used for grain refining of aluminum. Various stirring methods were developed, including mechanical stirring, electromagnetic stirring and bubble mixing [ 48, 49, 50 ]. Wannasin et al. [ 51] investigated bubble mixing process and obtained fine-grained alloys.
2015-11-23 An overview is given of grain refinement in aluminum casting alloys. The mechanisms involved and the benefits of refinement are described. The review shows that current practices were developed long before modern Al-Ti-B refiners became available, and are employed now largely for historical reasons.The results of tests in Al-Si, Al-Si-Cu, Al-Cu, Al-Mg

2016-2-1 Grain refinement leads, in general, to a decreased tendency to hot tearing, a more dispersed and refined porosity distribution, and improved directional feeding characteristics during solidification. Reduced as-cast grain size can also lead to improved mechanical properties and wrought processing by reducing the recrystallized grain size and achieving a fully

2020-12-10 RECENT DEVELOPMENTS IN GRAIN REFINING OF ALUMINIUM . Two different grain refining test methods were used to test the effect of commerdal and new binary and ternary aluminium master alloys on pure aluminium and high strength aluminium alloys. The influences of the amount of master alloy addition, pauring temperature and holding time were ...
The present invention relates to a method for grain refining of aluminium and aluminium alloys wherein a siliconboron alloy containing between 0.01 to 4.0 % by weight of boron is added to molten aluminium or aluminium alloy in such an amount that the resulting melt of aluminium or aluminium alloy contains at least 50 ppm boron. The invention further relates to a grain refining

2016-9-1 1.Introduction. Grain refinement in a casting ingot is a constant concern for metallurgists. In practice, engineering alloys usually consist of a variety of solute elements, which can readily generate a solute-rich boundary layer in front of the crystallizing interface, because most alloys have a solute redistribution partition coefficient that is less than unity.
