Book Description
A program of research was conducted to determine the effects of Al content and Ti3Al precipitation o the micro- and macroplastic behavior of Ti-Al alloys, and also to investigate the effects of Al content and Ti3Al on the susceptibility to, and mechanism of, stress corrosion cracking in a methanol - 1.5% HCl environment. The tensile microstrain parameters sigma sub E and sigma sub A increase with Al content. Tests on aged Ti-6 and Ti-8 wt. % Al material indicate that the influence of Ti3Al on the microstrain parameters and flow stress is athermal. Stress corrosion specimens which had been solution treated and quenched failed primarily by intergranular parting. Specimens in the aged condition exhibit a mixture of cleavage fractures and some intergranular parting. It is thought that stress corrosion failure in Ti-Al alloys proceeds as a consequence of anodic dissolution. (Author).

Book Description
Advances in Research on the Strength and Fracture of Materials: Volume 2Bs—Fatigue contains the proceedings of the Fourth International Conference on Fracture, held at the University of Waterloo, Canada, in June 1977. The papers review the state of the art with respect to fracture in a wide range of materials such as metals and alloys. This volume is comprised of 85 chapters and opens by discussing the metallographic aspects of fatigue in pearlitic structures and the dislocation diffusion mechanism of fatigue crack formation. The reader is then introduced to localized plastic deformation and fracture in slip bands during fatigue loading of age hardening aluminum alloys; the microstructure of fatigue fracture surfaces in titanium; mechanisms of liquid metal embrittlement, stress corrosion cracking, and corrosion-fatigue; and the fatigue behavior of macroscopic slag inclusions in steam turbo-generator rotor steels. A model for fatigue crack initiation in polycrystalline solids is also described. This monograph will be a useful resource for metallurgists, materials scientists, and structural and mechanical engineers.

Book Description
A further clarification of the mechanism of stress-corrosion cracking in 7075 aluminum alloy was obtained, particularly with regard to the role of dislocations in the mechanism and to the relationship between dislocation mobility and susceptibility to stress-corrosion cracking; high dislocation mobility reduces susceptibility. It was demonstrated during stress-corrosion tests on 7075-T73 specimens that had undergone prior plastic deformation, that the introduction of dislocations alone did not lower the dislocation mobility sufficiently to diminish the stress-corrosion resistance. This is in contrast to similar experiments with -T6 specimens, wherein precipitation was induced by similar deformation and the mobility was reduced sufficiently to lower the stress-corrosion resistance. An important role for immobilized dislocations was also suggested by a theoretical calculation of the stress field around an edge dislocation which neighbors a grain boundary precipitate. This calculation, which was based only on elasticity theory and thus precluded plastic flow, indicated that a large tensile stress, theoretically as high as 250,000 psi, could act normal to the precipitate-matrix interface. When the capacity for plastic flow (i.e., the dislocation mobility) was intentionally reduced by notching a stress-corrosion specimen, a rapid failure could be induced in normally resistant 7075-T73 alloy.
