摘要:... The effect of weld bead shape on weld fatigue strength using the tandem metal active gas (MAG) welding process was investigated by comparing with the direct current (DC) and DC pulse welding processes. For the same amount of deposited metal, the wire feeding speed was fixed...

摘要:Abstract(#br)High cycle fatigue performance is significantly affected by the surface conditions of mechanical components. Traditionally, one major effect of low plasticity burnishing process in promotion fatigue resistance has been ascribed to the generation of compressive residu...

摘要:Abstract(#br)In this study, the effects of micro-shot peening and artificial defect on the fatigue properties of EA4T railway axle steel were evaluated. Un-peened (UP) and micro-shot peened (MSP) EA4T axle steel specimens were drilled to introduce artificial defects on the surf...

摘要:Abstract(#br)Fatigue improvement techniques are widely used to increase fatigue strength of welded high strength steels. In this paper high frequency mechanical impact (HFMI) and a Low Transformation Temperature (LTT) filler material were employed to investigate the effect on fatigue strength...

摘要:Abstract(#br)This paper investigates the fatigue strength of two cast aluminium alloys, EN AC-45500 and 46200, dealing with the influence of microporosity and the statistical size effect. Small-scale round specimens are extracted from cylinder heads and crank cases as typical ...

摘要:Abstract(#br)Fatigue strength assessment of large-scale structures and components is usually performed on the basis of experimental results from small-scale specimens. A proper transfer from small specimens to large-scale structures requires the consideration of size and stress-g...

摘要:Abstract(#br)This paper contributes to quantify the influence of the local mean stress condition and the local weld geometry on the high-cycle fatigue strength of welded and high frequency mechanical impact (HFMI) treated S960 high-strength steel joints. A calculation procedure i...

摘要:Abstract(#br)High frequency mechanical impact (HFMI) is a recent post weld treatment method which can be employed to increase the fatigue strength of welded components. In this paper the fatigue strength of as-welded and HFMI treated fillet welds in a 1300 MPa yield strength...
