Relationship between casting modulus and grain size in cast A356 aluminium alloys [PDF]
Microstructure of Al-Si alloy castings depends most generally on melt preparation and on the cooling rate imposed by the thermal modulus of the component. In the case of Al-Si alloys, emphasis is put during melt preparation on refinement of pro-eutectic (

Taguchi Approach for Optimization of Parameters that Effect Grain Size of Cast A357 Alloy
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

Effects of grain refinement on cast structure and tensile properties of superalloy K4169 at high pouring temperature [PDF]
In order to improve the filling ability of large complex thin wall castings, the pouring temperature should be increased, but this will result in the grain coarsening. To overcome this problem, two kinds of grain refiners of Co-Fe-Nb and Cr-Fe-Nb ternary

Effect of Casting Temperature on Grain Size of Al-Si Alloys Refined by a Novel Grain Refiner
The automotive industry is willing of employing a greater amount of light metals like aluminium, magnesium and titanium, in order to reduce the total weight of the cars and, consequently, fuel consumption. Even though some casting aluminium alloys are commonly employed for automotive structural applications, their mechanical performances can be ...
