Special Issue Information

Dear Colleagues,

The application potential of engineering materials is related to their properties for the considered use. For metals, the potential exists to improve or tailor properties for specific and especially high-end applications through the processes affecting the microstructure evolution. These processes include heat treatment, thermomechanical treatment, severe plastic deformations processes, or basically processes of casting, welding, or recently additive manufacturing, which can play a significant role in the creation of the desired properties of traditional metallic materials. Currently available processes provide not only homogeneous materials but also yielding heterogeneous and functionally graded materials, such as additive manufacturing, laser processing, processing with inductive treatment. All considered processes produce a specific microstructure that is mirrored in distinct mechanical, physical, or thermo-physical properties that are required for engineering applications.

This Special Issue is focused on papers considering the relationships between microstructure and related properties for the application of advanced metallic materials. This Special Issue will collect quality papers providing a sound base in the field for present and future scientists dealing with the enhancement of metallic materials properties for specific high-end applications.

This study investigates multiple cyclic loading scenarios of non-oriented electrical steel sheets through both experimental and numerical approaches. The numerical simulations were conducted using Representative Volume Elements generated with DRAGen. DRAGen allowed for the generation of Representative Volume Elements with a non-cubic shape to cover the complete sheet thickness and enough grains to represent the material’s texture. The experimental results, on the other hand, are utilized to calibrate and validate a prediction model, highlighting the significance of accumulated plastic slip as a suitable parameter correlated with fatigue life. Using the accumulated plastic slip from the simulations, a fatigue fracture locus is introduced, which describes a 3D surface dependent on the maximum stress, fatigue life, and the fatigue stress ratio. The study shows reliable results for the fatigue life prediction using the calibrated fatigue fracture locus. While substantial progress has been made in predicting the fatigue life at multiple fatigue stress ratios, notable disparities between experimental and simulation results suggest the need for further investigations regarding the influence of the surface quality. This observation motivates ongoing research efforts aimed at refining simulation methodologies to better incorporate surface roughness effects. In summary, this study presents a validated model for predicting fatigue life in non-oriented electrical steel sheets, offering valuable insights into material behavior at different loading scenarios and informing future research directions for enhanced structural performance and durability.
