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. There are two main studies that are used to explain the nucleation of $\alpha$ particle. Neither of them have proven to be the one and only method of nucleation of $\alpha$ One by azimzadeh and Rack suggests that $\alpha$ particles nucleate near $\omega/\beta$ but at a certain distance. The argument in this paper is that alloying elements like Al are present in titanium alloys, are $\alpha$ stabilizers while $\omega$ destabilisers. SO the area around the $\omega$ are rich in Al content which promotes the growth of $\alpha$ particles in the vicinity of $\omega$ due to rejection. There is another speculation that the $\alpha$ plates form at the core of $\omega$, this process is known as displacive transformation. This is proven by using TEM and HRTEM, as mentioned in the introduction. It is however inconclusive as to which is mechanism is correct as although evidence for both techniques is present. If $\omega$ /$\beta$ did not play a significant role in the nucleation of $\alpha$ then there should be noticeable difference in the quantity of $\alpha$. However since alloys with low and high $\omega$ /$\beta$ boundaries show a significant difference in nucleation of $\alpha$ their affect cannot be ignored.This paper specifically explores: \begin{enumerate} \item The role of $\omega$ the intro granular nucleation of $\alpha$. Precipitates in ti5553 alloy containing the $\beta$. As well as $\alpha$ stabilizer. In this alloy Mo and V are $\beta$ stabilizer and Al is $\alpha$ stabilizer \item Investigate growth of different variation s of intragranualar $\alpha$ precipitates and the changed in the microstructure \item Observing the portioning of the alloying elements in the vicinity of $\alpha$ and $\beta$ particles \end{enumerate}
