Book Description
This publication reviews most of the available literature on the fatigue properties of β annealed Ti-6Al-4V and titanium alloys with similar microstructures. The focus is on β processed and β heat-treated alloys because β annealed Ti-6Al-4V has been selected for highly loaded and fatigue-critical structures, including the main wing-carry-through bulkheads and vertical tail stubs, of advanced high-performance military aircraft. An important aspect of the review is a concise survey of fatigue life assessment methods and the required types of fatigue data. This survey provides the background to recommendations for further research, especially on the fatigue behaviour of β annealed Ti-6Al-4V under realistic fatigue load histories, including the essential topic of short/small fatigue crack growth. Such research is required for independent fatigue life assessments that conform to the aircraft manufacturer’s design requirements, and also for life reassessments that most probably will have to be made during the service life of the aircraft.

Book Description
The report discusses the current situation in beta forging of titanium alloys, based on a literature search plus the author's personal interviews with both using and forging industries. Manufacturers and users of beta forgings are listed in the report. Strength and fatigue properties of beta forgings are described and compared with the properties in structures forged by conventional means. Control of properties by microstructural control is discussed and illustrated by several photographs. Forging designs and practices are discussed. (Author).

Book Description
The report discusses both theory and practice related to the occurrence and elimination of residual stresses in titanium and its alloys. Following a brief section on the general principles of heat treatment of titanium alloys, a description of the origin and effects of residual stresses due to forming, specifically, of the Bauschinger Effect, is presented. Additional data covers residual stresses due to mechanical operations such as grinding, shot peening, grit blasting, vibratory tumbling, and joining. Methods of treatment to eliminate residual stresses are described. (Author).

Book Description
The extrusion temperature and cooling rate after extrusion were varied for round to round axisymmetric extrusions of the Beta 111 titanium alloy. The microstructures after extrusion and after heat treatment were examined both by optical and transmission electron microscopy and correlated with the room temperature mechanical properties. Heat treatment following extrusion consisted of either aging only or a solution treatment followed by aging. In contrast to air cooling after extrusion, direct water quenching immediately after extrusion was effective in retaining a significant amount of dislocation structure from the hot deformation, the effect being greater at the lowest extrusion temperature. This retained dislocation structure effectively promoted the formation of alpha during aging and retarded the tendency for the omega phase to form. The effect was greatest when specimens were aged without the intermediate solution treatment. The greater amount and finer distribution of alpha obtained in this manner resulted in significantly higher tensile strengths, quite acceptable values of RA, but with a small loss in fracture toughness. For the extrusion temperature range investigated, the extrusion pressures for the Beta 111 titanium alloy were somewhat lower than for the older, more well established beta titanium alloy. he extrusion pressures for Beta 111 were also lower than for alpha and alpha plus beta titanium alloys, for temperature ranges where they have significant amounts of alpha present.
