Effect of Tempering Temperature on Microstructure and Sulfide Stress Cracking of 125 Ksi Grade Casing Steel.

The influence of tempering temperature on the microstructure of 0.5Cr0.4W steels was investigated by scanning electron microscope, and the roles of grain boundary character, dislocation, and Taylor factor in sulfide stress cracking (SSC) resistance were interpreted using the election backscattered diffraction technique.

Effect of Titanium and Boron Microalloying on Sulfide Stress Cracking in C110 Casing Steel.

The effect of Ti and B microalloying on the hardenability, prior austenite grain size (PAGS), mechanical properties, and sulfide stress cracking (SSC) of C110 grade steel was studied by Jominy testing, static tensile testing, an optical microscope (OM), scanning electron microscopy (SEM) and double cantilever beam (DCB) testing. The results show that the addition of 0.015% Ti and 0.

WITHDRAWN: A three-step electrochemical method designed for the production of nickel- and platinum-doped TiO(2) multi-nanoporous thin-film electrodes: An application in the degradation of acid red G.

This study reports on the production of the platinum- and nickel-doped anatase multi-nanoporous thin-film electrodes. These doped electrodes were fabricated from titanium plates by a three-step electrochemical method, which comprises (i) anodization of titanium plates in oxalic acid electrolyte, (ii) electrodeposition of transition metals on the oxide produced, and finally, (iii) re-anodization of the whole assembly in sulfuric acid electrolyte, which leads to the production of stable transition metal-doped TiO(2) thin-film electrodes. Some investigations concerning the degradation of a non-biodegradable azo dye (acid red G) in the presence of these electrodes irradiated by artificial UV-light were performed.
