The Influence of Ultrasonic Impact Treatment on Fatigue Behaviour of Welded Joints in High-strength Steel
The unabated growth of the steel industry and progressively increasing operating loads on metal structures generate a need for a search for optimum engineering solutions to improve the loadcarrying capacity and reduce metal consumption. One way of resolving this problem is to utilise high-strength steels. It is common knowledge however that the improvement of the steel strength is accompanied b...
متن کاملFatigue Properties of the Ultra-High Strength Steel TM210A
This paper presents the results of an experiment to investigate the high cycle fatigue properties of the ultra-high strength steel TM210A. A constant amplitude rotating bending fatigue experiment was performed at room temperature at stress ratio R = -1. In order to evaluate the notch effect, the fatigue experiment was carried out upon two sets of specimens, smooth and notched, respectively. In ...
متن کاملNotch fatigue behavior: Metallic glass versus ultra-high strength steel
Studying the effect of notch on the fatigue behavior of structural materials is of significance for the reliability and safety designing of engineering structural components. In this work, we conducted notch fatigue experiments of two high-strength materials, i.e. a Ti32.8Zr30.2Ni5.3Cu9Be22.7 metallic glass (MG) and a 00Ni18Co15Mo8Ti ultra-high strength steel (CM400 UHSS), and compared their no...
متن کاملEnhancing Fatigue Strength by Ultrasonic Impact Treatment
Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated in large-scale specimens having a nominal yield strength of 345 to 690 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating them by UIT. A par...
