Small Creep Deformations and Residual Stress Relaxation in Welded and Shot Peened Al Mg Si Cu-aluminum Alloys
The stability of compressive residual stresses and the stability of strain hardening states are seen to have high technical importance. For a laser beam welded AlMgSiCu-alloy, results of applied stress and residual stress relaxation at elevated temperatures 100<T<150°C are presented. These experiments prove the existence of back stresses. The level of these stresses can be estimated to be in th...
متن کاملThermoelectric Nondestructive Evaluation of Residual Stress in Shot-Peened Metals
This paper presents a noncontacting thermoelectric method that can be used to characterize the prevailing residual stress in shot-peened specimens. This novel method is based on magnetic detection of local thermoelectric currents in the compressed near-surface layer of metals when a temperature gradient is established throughout the specimen. Besides the primary residual stress effect, the ther...
متن کاملFatigue of Friction Stir Welded 2024-T351 Aluminium Alloy
Fatigue failure characteristics of friction stir welds in 13mm gauge 2024-T351 plate have been assessed. Failure occurred from either the weld region (nugget/flow arm) or from the material immediately surrounding the weld. Fatigue failure from the surrounding material was essentially conventional, initiating from large S-phase intermetallic particles and growing in a macroscopic mode I manner. ...
متن کاملA Coupled Creep-plasticity Model for Residual Stress Relaxation of a Shot-peened Nickel-base Superalloy
A COUPLED CREEP-PLASTICITY MODEL FOR RESIDUAL STRESS RELAXATION OF A SHOT-PEENED NICKEL-BASE SUPERALLOY Name: Dennis Justin Buchanan University of Dayton, 2007 Advisor: Dr. R. A. Brockman Shot peening has been employed in numerous industries for decades to impart beneficial compressive residual stresses on the surface of metal components. Compressive residual stresses retard initiation of surfa...
متن کاملLaser-ultrasonic surface wave dispersion measurements on surface-treated metals.
Surface acoustic wave (SAW) velocity spectroscopy has been long considered to be one of the leading candidates for nondestructive characterization of surface-treated metals because of its ability to probe the material properties at different penetration depths depending on the inspection frequency. We developed a high-precision laser-ultrasonic technique to study the feasibility of SAW dispersi...
