Low cycle fatigue tests are performed on specimens of niobium stabilized austenitic steel AISI 347 (1.4550) at ambient temperature. During the test, the fatigue specimens are equipped with eddy current probes, and it can be seen here that the impedan

In general, formed components are lightweight as well as highly economic and resource efficient. However, forming-induced ductile damage, which particularly affects the formation and growth of pores, has not been considered in the design of component

The residual stress state in the subsurface is a key element of surface integrity. It is well known to have a significant impact on a component's properties in terms of fatigue behavior and resistance to wear and corrosion. For this reason, adjusting

The authors optimized the processing parameters of laser shock peening (LSP) of stainless steel, taken as a representative metal, using a Ti:sapphire laser with pulse durations in the range of 100 fs–2 ps. It was found that direct exposure of the m
