Efficacy of Borides in Grain Refining Al-Si Alloys
(2018)The grain refining efficacy of titanium, aluminum, and niobium borides, as well as niobium aluminides, introduced via commercial and lab made master alloys on Al-Si alloys was investigated. Significant grain refinement is ... -
Engineering the heterogeneous nuclei in Al-Si alloys for solidification control
(2016-12)Aluminium alloys are particularly advantageous for transportation industries to reduce the weight of the vehicles and thus pollution. The optimisation of the performances of Al alloys can be achieved by engineering and ... -
Formation of equiaxed crystal structures in directionally solidified Al-Si alloys using Nb-based heterogeneous nuclei
(Nature Publishing Group: Open Access Journals - Option C, 2016)The design of chemical compositions containing potent nuclei for the enhancement of heterogeneous nucleation in aluminium, especially cast alloys such as Al-Si alloys, is a matter of importance in order to achieve homogeneous ... -
Heterogeneous Nb-Based Nuclei for the Grain Refinement of Al-Si Alloys
(Springer, 2016)Nb-based intermetallics are, generally, low-density high-temperature materials used for structural applications or cryogenic superconductors. In this work, we report the development of an Al(96)-Nb(2)-B(2) master alloy ... -
Nb-based heterogeneous nuclei for enhanced α-Mg nucleation in Mg(-Al) alloys
(Elsevier, 2016-04-15)The effect of the introduction of in-situ formed Nb-based compounds on Al-including Mg alloys has been investigated. It is found that grain refinement is consistently achieved. Nb-based intermetallic particles are responsible ...
