intergranular stress corrosion cracking growth perpendicular to fatigue pre cracks in t l oriented compact tension specimens in simulated pressurized water reactor primary water
Corrosion Science, 2014Co-Authors: Seiji Yaguchi, Toshio YonezawaAbstract:Abstract Intergranular Stress Corrosion Cracking (IGSCC) growth observed perpendicular to the Plane of fatigue pre-cracks in T–L oriented compact tension specimens made of highly cold-rolled Type 316 stainless steel has been investigated metallurgically. One-directional cold Rolling resulted in significant lamellar local strains on the Plane parallel to the Rolling Plane. Oxide was detected along intergranular crack. It is deduced that intergranular cracking was due to selective oxidation and enhanced high diffusivity at grain boundaries coupled with lamellar local strains. It is argued that strain-induced oxidation could be a possible mechanism for IGSCC in cold-rolled stainless steels in simulated Pressurized Water Reactor environment.

Effect of heat-treatment on the texture and anisotropy of transformation strain in Ti-Ni-Fe rolled thin plates
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 1999Co-Authors: Anak Khantachawana, Shuichi Miyazaki, H. Iwai, Manfred KohlAbstract:Abstract Rolling and annealing processes were applied to make Ti–50.5Ni–0.4Fe (at.%) thin plates. Such processes create a specific texture in the plates, and the texture causes an anisotropy of transformation strain to appear. The purpose of this study is to investigate the effect of annealing on the texture and anisotropy of the transformation strain in Ti–50.5Ni–0.4Fe (at.%) plates with a cold-Rolling reduction of 37.5% and a thickness of 100 μm. They were annealed at 673, 873 and 1273 K, respectively, for 3.6 ks. A crystallite orientation distribution function (ODF) was measured by using diffraction from {110}, {211} and {200} Planes. Inverse pole figures were drawn on the basis of the ODF. Using the crystallite axis density in the inverse pole figures, the transformation strain was calculated as a function of the angle from the Rolling direction (RD) in the Rolling Plane. In the Rolling Plane, the transformation strain was almost constant in a range of the angles from 0 to 30°, and decreased with a further increase of the angle. The anisotropy of the transformation strain in the Rolling Plane became strongest in a specimen annealed at 873 K.

Toughness anisotropy in X70 and X80 linepipe steels
Materials Science and Technology, 2013Co-Authors: Min Sung Joo, Dong-woo Suh, Jin-ho Bae, H. K. D. H. BhadeshiaAbstract:The anisotropy of mechanical properties in the context of steels used to fabricate large diameter pipes can be detrimental to the design and performance of the pipes. We examine here the anisotropy of strength and toughness, and with the help of detailed characterisation show that there is a complex interaction between the ability of the steel to delaminate on the Rolling Plane and the crystallographic texture, which promotes brittle fracture on the macroscopic fracture Plane of Charpy specimens.

Recrystallization textures in tantalum sheet and wire
International Journal of Refractory Metals and Hard Materials, 2000Co-Authors: Clyde L. Briant, Erin F. Macdonald, R.w Balliett, T LuongAbstract:Abstract This paper presents a study of the evolution of recrystallization texture in tantalum. Both rolled sheet and drawn wire are considered. The rolled product developed a recrystallized texture in which the Rolling Plane normal was parallel to 〈1 1 1〉 . There was no specific direction parallel to the Rolling direction; rather this direction varied so that the Rolling Plane orientation could be accommodated. In the drawn wire, the recrystallized texture was one in which 〈1 1 0〉 was parallel to the deformation direction.
