\begin{itemize}  \item  The other process is when $\alpha$ forms around the boundary of $\beta$. This process occurs when $\beta$ is slowly cooled. However this process also contribute to yield stress of titanium , though to a smaller extent. this is because the formation of $\alpha$ around boundary are large particles and are prone to plastic deformation and subsequent cracking. This kind of $\alpha$ formation only provides boundary hardening but does not prevent dislocation from moving through the grains. This mechanism can be used to control the toughness after precipitation hardening described above. A two stage annealing process can be used to nucleate $\alpha$ particle on the boundaries of $\beta$ matrix and the second stage can be used to increase grain size until desired hardenability is obtained. \begin{itemize}
