Alpha alloys

Table 2 summarizes the best data obtained in three groups of alloys namely binary, ternary and complex alloys with combined strengthening with borides and silicides. The binary alloys is practically quasi-binary ones because contain enough content of iron, which transforms these formally alpha-alloys into practical pseudo-alpha ones containing small but important amount of beta-phase. 

Many different titanium alloys have been developed for a large variety of applications. Titanium alloys are generally classified according to the equilibrium phases present in their microstructure at room temperature (Ref 1). They can be classified as commercially pure (CP) alloys and alpha alloys that mainly contain the hep phase, alpha-beta alloys that contain both phases, and metastable beta alloys and beta alloys that consist largely of the bcc phase. 

Group III Other Alpha and Near-Alpha Alloys ... 

Near-alpha alloy with excellent weldability, seawater stress corrosion cracking resistance, and high dynamic toughness. 

Titanium alloys have the best corrosion resistance of the metals and alloys typically used in seawater. Titanium is a passive film-forming alloy and retains excellent resistance in both low and high velocity seawater. Some titanium alloys, specifically the all alpha and near-alpha alloys, do exhibit a susceptibility to stress corrosion cracking [72].
