Abstract

Several studies, dating back to 1950s, were conducted on the addition of boron to titanium alloys, with an aim to improve the stiffness and strength. The majority of these efforts did not lead to successful transition due to shortfalls in mechanical property combinations and insufficient understanding of the effect of boron addition on processing-microstructure-property relationships. Recently, a team of researchers critically evaluated boron-modified titanium alloys to assess their applicability for aerospace applications. Several unique opportunities offered by boron-modified Ti alloys were discovered during these evaluations. Boron is essentially insoluble in titanium and precipitates as fine TiB whiskers. Small additions (~0.1 wt%) of boron to titanium alloys were found to result in dramatically finer grain sizes in the as-cast condition. The presence of TiB precipitates restricts the grain growth at elevated-temperatures, even above the beta transus. Together, these features offer the potential to develop affordable thermo-mechanical processing paths for titanium alloys. This recent work also demonstrated that, via small boron additions, the strength and stiffness of conventional titanium alloys could be increased up to 20% while retaining acceptable fracture and fatigue properties. In this paper, we review this new class of titanium alloys and describe unique benefits obtained via microstructure engineering that were discovered in several recent studies by the authors and their collaborators.
