Note: Temperature-time-transformation diagram of three Beta Ti alloys, relative to their Beta transus [180].
In addition to Ti3Al, grain-boundary Alpha (GB-Alpha) phase is also causes a decrease of fracture toughness. When cooling from Beta phase region, Alpha phase nucleates preferentially on Beta grain boundaries. With a small undercooling where the driving force of Beta -> Alpha is small, Alpha phase can grow along Beta grains and thicken, forming a continuous network of Alpha layer. However, with a large undercooling (and large driving force), Alpha phase grows to the inside of Beta grains in the form of Widmanstatten plates in colonies. Isothermal temperature-time-transformation (TTT) diagrams of three Beta Ti alloys have shown that GB-Alpha is most likely to form at 100-200 C below Beta transus [180]. In order to inhibit or bypass GB-Alpha formation, the Beta -> Alpha transformation should be slowed before Widmanstatten plates become dominant.
