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.
