For a reliable design of structural components, valid information about the fatigue strength of the material used is a prerequisite. As the determination of the fatigue properties, and especially the fatigue limit σw, requires a high experimental ef

Alternatively to conventional stress-strain hysteresis measurements in this paper physically based materials data such as specimen temperature, electrical resistance, speed of sound or generator power are used to describe the cyclic deformation behav

Thin strips of electrochemically deposited nanocrystalline nickel-iron with thicknesses of 320 or 330 µm are modified by defined grinding. Small changes in the cutting depth and the variation of the grinding process, up cut or down cut, result in di

Short-time procedures for determining the fatigue properties of materials can provide significant improvements in cost efficiency and are therefore of great scientific and industrial interest (Jost et al., 2017). A promising short-time procedure is P

In recent years, deformation induced surface hardening when turning was carried out to enhance the component performance of metastable austenitic steels. To induce such a phase transformation from austenite to martensite in the workpiece surface laye
