\section{Introduction}  Titanium is a light metal that is used in a range of application in the industry from aerospace industry to creating medical devices. Titanium possesses excellent strength and is a tough yet lightweight metal. It is widely used because of its resistance to corrosion and biocompatibility. In order to make titanium a more reliable metal to use in the industry alloys have been created in order toproduce  enhance the strength and toughness of titanium. The aim of this paper is to understand the different methods of $\alpha$ nucleation in titanium alloys as well as understating the effects of it appearance and morphology on it strength.
