Special Issue Information

Dear Colleagues,

As the guest editor of the following Special Issue of Materials, I would like to invite you to contribute a research paper to the Issue on the topic of “Improving Alloy Material Performance: Alloy Design and Structural Modification”. The Issue will cover several scientific problems. Among them, the main focus will be aimed at alloy design (new alloys composition, influence of alloying elements on properties of common alloys, and new alloys processing leading to structural changes), a description of the microstructure influence on the improvement of alloy properties (e.g., additive manufacturing, powder metallurgy processing, rapid solidification, and grain boundary engineering), and the new unique properties of alloy materials (e.g., self-reporting materials, self-healing materials, and biodegradable alloys).

I would greatly appreciate a reply to this invitation, letting us know whether you would like to contribute.

We look forward to collaborating with you in the near future.

Dr. Alena Michalcová

To investigate the relationship between inclusions and bending fatigue behaviors in 20Cr2Ni4 steel under different stress concentrations. This paper designs a new experimental method to prefabricate different size stress concentrations near the inclusions, and then conducts a new type of bending fatigue test to study the inclusions and their surrounding stress distributions in 20Cr2Ni4 steel. A microhardness tester was combined with laser etching equipment to realize the prefabrication of different stress concentrations at arbitrary positions around any inclusion on the gear steel surface. This method provides an experimental basis for the quantitative analysis of the relationship between stress distribution and fatigue life around the inclusions of heavy-duty gear steels. We also predict the bending fatigue lives of heavy-duty gear steels with different types of inclusions, stress states, and spatial distributions. Then, based on the prefabricated notch parameters and the state of inclusions in the steel, a mathematical model of quantitative analysis is proposed, which can accurately predict the fatigue limit of heavy-duty gear steel. The research results can be applied to the actual use of heavy-duty gears and to the accurate life estimation based on the state of gear stress, thereby providing a quantitative reference model for subsequent gear steel production and gear part processing.
