摘要：

Boron refinement is an established method to refine the grain structure of titanium alloys. The effect of boron on microstructure of multicomponent Ti-Nb-Cu-Co-Al-B alloys was studied. These as-cast alloys exhibit a composite-like microstructure consisting of about 92 vol% of beta-Ti dendrites surrounded by an ultrafine-structured eutectic composed of beta-Ti and B2 TiCo. It was found that significant additions (up to 1 at%) of boron do not result in a pronounced refinement of microstructure in these alloys. However, noticeable strengthening and stiffening effects are observed for the alloys with increasing boron concentration. In particular, the yield strength of Ti-13.6Nb-6Co-5.1Cu-6.5Al (at%) improves from 1110 +/- 30 MPa to 1200 +/- 30 MPa with addition of 1 at% of boron. Additionally, increasing boron content affects the morphology of the eutectic structure causing its degradation. (C) 2015 Elsevier B.V. All rights reserved.
