| Abstract | Effect of boundary (beta/beta and alpha/beta boundary) on the alpha phase precipitation in a near-alpha titanium alloy had been statistically investigated. The result shows that most grain boundary alpha(GB alpha) precipitates maintain a Burgers orientation relationship (BOR) with one of adjacent prior beta grains. However, in some unique cases, the GB alpha did not maintain a BOR with either prior beta grains due to preferential growth of equiaxed primary alpha (alpha(p)). It was also observed that the low-angle beta/beta boundaries can be passed through by secondary alpha (alpha(s)). Additionally, when an alpha(p) grain and an adjacent beta grain have a near BOR, the preferred as may form at alpha(p)/beta boundary with the similar orientation to the alpha(p) due to low interfacial energy of low-angle alpha(p)/alpha(s) boundary.
