Effect of strain path and the magnitude of prestrain on the formability of a low carbon steel: on the textural and microtextural developments

Article Abstract:

The textural developments of the low carbon steel were characterized by X-ray orientation distribution function (ODFs) and were simulated using different Taylor type deformation texture models. The significant features of the substructures were strain localizations, where both in-grain rotations and estimated stored energies depend on the relative appearance of the strain localization and are distinctly related to the textural softening.

Measurement and microstructural evaluation of creep-induced changes in magnetic properties of a 410 stainless steel

Article Abstract:

A study is conducted that evaluated the use of quasi static hystereis measurements as a possible procedure to evaluate creep in a 410 martensitic stainless steel, a material used in powerplant components. On comparison of the micsrostrcutural changes with the magnetization changes, it is determined that the changes in the hystereis curves were clearly detectable and correlated with the creep-induced damage.

Initiation and propagation of stress-assisted corrosion (SAC) cracks in carbon steel boiler tubes

Article Abstract:

The stress-assisted corrosion (SAC) cracks initiation and propagation in carbon steel water-wall tubes of industrial boilers by conducting slow strain rate tests are studied. Dissolved oxygen in boiler water has significant effect on crack initiation.
