Grain coarsening was achieved by heat treatment, and grain size...

...B.T. Lu; J.L. Luo; B. Peng; A. Palani; Y.C. Lu The effects of dissolved lead on the anodic dissolution behavior of Alloy 690 (UNS N06690) were experimentally investigated in an alkaline solution that is used to simulate the environment in a nuclear steam generator crevice. Lead inoculation...

.... The most susceptible steel was the quenched steel followed by the quenched and tempered steel, whereas the least susceptible was the as-received steel. The cracking mechanism is discussed in terms of the anodic dissolution and film rupture. Present address: UAEM, Centro de Inv. en Ingenieria y...

... spectrometry (SIMS). Results showed hydrogen could diffuse into the steels around the crack tip during the SCC process. Hydrogen facilitated the dissolution rate of the steel in the solution and increased SCC intensity. A mechanism was proposed that showed hydrogen enhances the anodic dissolution type of SCC...
