Abstract

Trace additions of boron to commercial purity titanium result in significant microstructural changes. Changes include the promotion of dendritic growth and refinement in both the prior-β and α-grain size. Boron partitions strongly on solidification and TiB intermetallics are observed throughout the microstructure, confined to interdendritic regions. This strong partitioning of solute causes prior-β grain refinement, and the presence of TiB intermetallics and/or the increased β-grain boundary surface area associated with the change in β-grain morphology assists nucleation of the α-phase.
