“…During cyclic loading, shear along preferential crystal-lographic planes will occur on the positive tensile loading portion of the cycle, promoting formation of a slip step and access to newly generated bare metal [38]. Blackburn and Williams agree with the theory of formation of a large slip step for crack nucleation [27]. Gaseous hydrogen chloride continues to react with newly exposed metal, extending channels deeper into the base alloy until the supply of 435 HCl is exhausted.…”

“…Some authors attribute the apparent symmetry to decohesion along α-β interfaces, based on arguments suggesting hydrogen to segregate at these regions [23,24,25]. Other authors discuss possible combinations of mechanisms for crack propagation, including that of cleavage [26,27]. It is suggested that transgranular cleavage through the α-phase platelets could result in the mirrorlike appearance of these features on opposing sides of the fracture surface.…”

“…In either instance, embrittlement enables crack advance from the channel root at stress intensities below that required for cracking bulk, uncharged material. It is proposed that crack advance occurs by transgranular cleavage of the alpha phase [27] along preferred slip planes [8].…”

An unexplained feature was observed at the fatigue crack origin of a number of α/β titanium specimens tested at 450• C in the low cycle fatigue regime. The origin was discoloured blue but this was not a result of temper colouration; this feature sometimes resulted in large reductions in fatigue lives. A number of specimens were examined to determine the cause and formation mechanism of these "blue spots." This feature was associated with elevated oxygen and chloride levels and the presence of sodium. A mechanism based on hot-salt stress-corrosion cracking is proposed and the implications for service components are discussed.

“…The SCC susceptibility of alpha-phase alloys can also be complicated by the impurity iron content; this iron can stabilize up to about 5% of beta-phase content. On lowtemperature aging the beta phase alters to a beta-plus-omega structure, which may lower the threshold stress intensity factor for SCC (Kjscc) for such alloys (Blackburn, Feeney, and Beck, 1973). Presumably TiCode-12 may exhibit similar behavior.…”

Because of the high level of biocompatibility, low level of corrosion, and excellent mechanical properties, titanium and many of its alloys have found extended use as the metal of choice for many implant applications. In addition, because of these properties there continues to be research on the properties of these alloys as well as prolific research and development of new titanium alloy systems. The newer β ‐titanium alloys have shown promise for applications where a lower modulus of elasticity is desirable. Newer alloys being developed must meet the primary requirement of biocompatibility as well as having the desired mechanical properties
