Prediction of Solidification Microstructure and Columnar-to-equiaxed Transition of Al–Si Alloy by Two-dimensional Cellular Automaton with “Decentred Square” Growth Algorithm
A Cellular Automaton (CA)-Finite Difference (FD) coupling model was developed to analyze the evolution of solidification microstructure and the columnar-to-equiaxed transition (CET) in AI-Si alloy.Expand
Grain refinement of hypoeutectic Al-Si alloys with B
Abstract The enhanced grain refining efficiency of B in treating hypoeutectic Al-Si alloys has been identified for more than 30 years. However, its exact underlying mechanism remains to be explored.Expand
Thermodynamic evidence for a poisoning mechanism in the Al–Si–Ti system
Abstract The poisoning of grain refinement in aluminium alloys owing to the presence of silicon is investigated using CALPHAD based thermodynamic modelling software. The existence of primary phasesExpand
Understanding mechanisms of grain refinement of aluminium alloys by inoculation
Abstract For over half a century, grain refinement of aluminium alloys has been achieved by chemical inoculation; current grain-refinement practice involves the addition of master alloys (e.g. Al –Expand
Effect of silicon content in grain refining hypoeutectic Al–Si foundry alloys with boron and titanium additions
Abstract The effect of Si content on the grain refinement of hypoeutectic Al–Si alloys was investigated. Alloying with Si refines the grain structure, which tends to be coarse and columnar inExpand
The effect of grain refinement and silicon content on grain formation in hypoeutectic Al–Si alloys
The effect of increasing the amount of added grain refiner on grain size and morphology has been investigated for a range of hypoeutectic Al-Si alloys. The results show a transition in grain size atExpand
Grain refinement of Al–Cu foundry alloys with B additions
Abstract Cu provides a grain refining effect for aluminium alloys that starts to deteriorate at ∼6 wt-%Cu. There is no improvement in grain size over that already obtained with 4–5 wt-%Cu when AlCu4Expand
Effect of solute Si and Cu on grain size of aluminium alloys
Abstract The relationship between grain size and growth restriction factor (GRF) and solidification interval at hypoeutectic solute concentrations was investigated in Al–Si and Al–Cu binary alloys.Expand
Mechanism for Si Poisoning of Al-Ti-B Grain Refiners in Al Alloys
Al-5Ti-1B is the most widely used grain refiner for Al alloys. However, it is not effective for grain refining Al alloys containing more than 3 wt pct Si. This adverse effect of Si is referred to asExpand
Performance of Al–5Ti–1B and Al–3B grain refiners in investment casting of AlSi7Mg0··3 alloy with preheated ceramic moulds
Abstract The performances of Al–5Ti–1B and Al–3B grain refiners were investigated when casting AlSi7Mg0··3 alloy into preheated ceramic shell moulds. The former is a poor grain refiner when castingExpand
