Because Ti-5553 consist of 5 alloying elements, namely Al, Mo, V, Cr, and Fe, varying the heating temperature also affects the partitioning of these elements in the $\beta$ matrix, this phenomenon is significant to the formation of $\alpha$ particles and the overall properties of the alloy because the elements are either $\beta$ stabilizer or $\alpha$ stabilizers and therefore govern the nucleation of these phases at different sites. Moreover presence of oxygen and hydrogen in the alloy also play a significant role in the development of microstructures as well as the determining its strength.  According to the paper $\alpha$ nucleates in the $\beta$ phase at various locations mostly associated with defects, and grain boundaries namely pre-existing boundaries in $\beta$ phase and $\beta$/$\omega$ interface and $\beta$/$\beta$’. $\alpha$ nucleation is also observed at dislocations and as  well as the boundaries between the alloying elements. The nucleation of $\alpha$ in this location depends heavily on the type of  heat treatment the alloy has undergone. \subsection{Obtaining $\alpha$ Through Quenching}  The process of obtaining well-distributed $\alpha$ particles is tough becausethe mostly  they mostly  nucleate at grain boundaries. To achieve a 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 uniformly  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 Below  is observed that for large misfits the $\alpha$ nucleate on ledges and dislocations an image  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 phase diagram  of these types of alloys have shown a $\omega$-assisted nucleation of $\alpha$ particles. changes.  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}
