Effect Of Localized Stress On Initiation Of IGSCC

Product Number: ED22-17308-SG

Author: Takaharu Maeguchi, Kyohei Hayakawa, Kimihisa Sakima, Tomotaka Miyazawa

Publication Date: 2022

In a polycrystalline material, the stress distribution on a microscopic scale is not uniform due to the elastic anisotropy and slip systems of constituent crystal grains. This leads to localized high stresses, especially at grain boundaries, when a load is applied to the material. In this paper, this localized stress is called as “microscopic stress”, distinguishing it from that in a homogeneous continuous body.

Evaluation On Applicability Of Nickel-Base Alloy Weld Materials With High Chromium Content In BWR Environment

Product Number: ED22-17130-SG

Author: Takahiro Hayashi, Yoshinori Katayama, Daiki Tanaka, Yumiko Tsuchiya, and Hidenori Takahashi

Publication Date: 2022

$20.00

Ni-base alloy weld material has been widely used for primary reactor components of BWR. Stress corrosion cracking (SCC) in Ni-base alloy welds is of an increased importance and an ongoing subject in the industry to secure material reliability of the components especially for long-term operation of light water reactors. Although alloy 82 has shown excellent service performance in BWR applications, it is known that alloy 82 exhibit SCC susceptibility in laboratory tests under simulated BWR environment with a combination of particular, severe test conditions such as high level of material cold work and highly accelerated environment. In addition, few experiences with SCCs in the welds associated with alloy 82 have been recently reported in the operating BWR plants.
