Evaluation of residual stresses in titanium alloywelded by tig using ultrasonic method and effectof the microstructure on the lcr elastic wave

The realized experimental measures of residual stresses proved that welding modified the stress state within the steel plate creating tensile stresses at the weld toe. These

The nanoindentation measurements were performed under load-control mode at room temperature using the Dynamic Stiffness Measurement (DSM) method [10]. Sixteen

the magnitude of the residual stresses decreases (for both side AD and RT) upon a change in velocity from 1200 to 1400 rpm whit a “M” shape increases in width. However, when

The aims of this study are (1) to determine the timing of afforestation at the beginning of the Holocene, (2) to reconstruct the vegetation history and natural species

Dans notre étude chez les adolescents, la prise en compte d’une comorbidité dépressive (mesurée par les critères DSM-IV-TR de l’état dépressif majeur) a permis d’affiner

The residual stresses evolution have been explained by the heterogeneous modifications of the microstructure particularly a marked decrease in the grain size, a high modification of

The goal of this work was to determine the longitudinal residual stress distribution in a TIG weld on Ti- 6Al-4V and to compare the stress distribution to the

The comparison of the two kinds of loading has shown that the pressure pulse magnitude from spherical bubble collapse is higher than the impact pressure of the micro-jet..
