X-RAY DIFFRACTION TECHNIQUE APPLIED TO STUDY OF RESIDUAL STRESSES AFTER WELDING OF DUPLEX STAINLESS STEEL PLATES

X-Ray diffraction technique applied to study of residual stresses after welding of duplex stainless steel plates

Duplex stainless steel is an example of composite material with approximately equal amounts of austenite and ferrite phases.Difference of physical and mechanical properties of component is additional factor that contributes appearance of residual swuart stresses after welding of duplex steel plates.Measurements of stress distributions in weld regio

The control of deliberate waiting strategies in a stop-signal task

To inhibit an ongoing flow of thoughts or actions has been largely considered to be a crucial executive function, and the stop-signal paradigm makes inhibitory control measurable.Stop-signal tasks usually combine two concurrent tasks, i.e., manual responses to a primary task (go-task) are occasionally countermanded by a stimulus which signals parti
