On the Correlation between Morphology of alpha and Its Crystallographic Orientation Relationship with TiB and Beta in Boron Containing Ti-5Al-5Mo-5V-3Cr-0.5Fe Alloy (Preprint)

Abstract

While the role of borides on the microstructure of titanium alloys has been discussed in many previous reports, this paper presents the first experimental evidence of (a) the three-dimensional geometry of alpha precipitates confirming their equiaxed morphology, as determined by reconstruction of serially-sectioned scanning electron microscopy images and, (b) the influence of crystallographic orientation relationship between Beta, TiB, and alpha phases on the morphology of alpha precipitates, investigated via detailed orientation microscopy studies on a boron containing version of the commercial Ti-5Al-5Mo-5V-3Cr-0.5Fe (Ti5553) alloy.
