The beta grain size of forged and beta heat treated titanium alloys is crucial in determining component properties. However, the metallurgical factors influencing the beta heat treated grain size remain inadequately understood. This study investigates the kinetics of beta grain growth and the impact of processing variables on grain size and growth behavior. We identified at least two distinct types of grain growth behavior; the most rapid growth aligns with classical steady-state behavior, while other kinetic types suggest some restriction in grain boundary mobility. Both behaviors may manifest in any alpha-beta or near alpha alloy, and once established, the growth kinetics appear relatively unaffected by subsequent processing. Factors possibly responsible for the observed distinctions are discussed, underscoring the importance of consistent process control. This study involved three different alloys, with near alpha alloys IMI 685 and IMI 829 examined most closely as they are widely used in the beta heat treated state. Grain growth behavior was also compared with an alpha beta alloy, IMI 318. Heat treatments were conducted at temperatures ranging from 1050°C to 1200°C to establish grain growth kinetics, revealing significant insights into processing impacts.
