\subsection{Obtaining $\alpha$ Through Quenching}  The process of obtaining well-distributed $\alpha$ particles is tough because the mostly they nucleate at grain boundaries. To achieve a well-distributed uniformly dispersed  formation of $\alpha$ particle titanium is solution treated above the $\beta$ transus temperature and quenched to form athermal $\omega$. The $\omega$ sites are well distributed throughout the $\beta$ matrix and when aged the $\omega$ coarsens and act as heterogeneous sites for $\alpha$ particles. As a result of distribution of $\omega$ the $\alpha$ forms is well distributed in the $\beta$ matrix and also exhibits morphologies that are distinctly different to $\alpha$ formed at higher temperatures. ****************  In this paper formation of $\alpha$ particles have been studied in alloys with large misfits between $\omega$ and $\beta$ phase as well as alloys with lower $\omega$/$\ $ misfits. It is observed that for large misfits the $\alpha$ nucleate on ledges and dislocations of $\omega$/$\beta$ interface. Large system has cube shaped $\omega$ precipitates. When coarsened the $\omega$ loses coherency with the $\beta$ matrix resulting in a nucleation site is $\alpha$. In low misfit $\omega$ is spherically or ellipsoid ally sharped and these do not show significant evidence of being potential nucleation sites for $\alpha$. However a 2 stage aging process of these types of alloys have shown a $\omega$-assisted nucleation of $\alpha$ particles.
