Stress relaxation behaviour in IN718 nickel based superalloy during ageing heat treatments

Modelling of Thermomechanical Fatigue Stress Relaxation in a Single-Crystal Nickel-Base Superalloy

A 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...

The stress concentration of In718 superalloy after friction welding and compare with Mar-M247 and In718 welded joints

Friction stir welding (FSW) is a new method that the joining is carried out by friction between two metals and heat creation. The stress concentration phenomena in welded joint cause the stress increasing in welded zone. In this research, modeling and analysis of similar junction of IN718 and Mar-M247 and non-similar junction of IN718-Mar-M247 superalloys were performed by ANSYS Software and fi...
