  \end{itemize}  The alloy under investigation in the paper is Ti-5553, which is more formally known as T- Ti-  5 Al-5Mo-5V -3Cr-0.5 Fe, is near $\beta$ titanium. This alloy exhibit the maximum strength of 1250 MPa and room temperature UTS to be as high as 1138-1172 MPa. Its properties include having high deep hardenability while still maintaining ductility and toughness. It is also able to endure high cycle fatigue, which makes it a very versatile and useful metal. However one of the major disadvantages of this alloy is that the properties of Ti-5553 vary over wide range conditions, this is because the properties are critically dependent of the microstructure of the alloy. It is therefore the purpose of this study to determine nature of this alloy and to understand its properties as well as investigate methods to keep them consistent in order to ensure that it can be dependable material for application. As mentioned before, the properties of this alloy heavily depend on the microstructure of titanium the study proposes that the nature of the Ti-5553 depends on the formation of $\alpha$ phase in the $\beta$ matrix. The volume fraction, morphology size and distribution of $\alpha$ particle in the $\beta$ matrix are the main drivers of noticeable change properties of Ti-5553. There are a number of ways that can be used to alter formation of $\alpha$
