Special Issue Information

Dear Colleagues,

Advanced high-strength steel stands as a cornerstone material that powers innovation and progress across numerous industries. From automotive manufacturing to aerospace engineering, and from structural buildings to precision machinery, its exceptional strength-to-weight ratio and enhanced properties have revolutionized the way we design and build.

In recognition of this vital role, we are excited to announce the publication of a Special Issue dedicated to "Advanced High-strength Steel". This initiative aims to bring together the brightest minds in the field to share their latest research, insights, and applications.

This Special Issue aims to cover the recent progress in the research field of steel, including phase transformations, mechanical properties, fatigue, precipitation, characterization, thermodynamic simulations, crystallography, materials processing, additive manufacturing, etc.

You are cordially invited to contribute your manuscript to this Special Issue. We enthusiastically welcome full-length papers, brief communications, and comprehensive reviews on these topics. Your insights will enrich the dialogue on this critical subject matter.

The very high cycle fatigue (VHCF) strength of welded joints made of high-strength structural materials is generally poor, which poses a serious threat to the long life and reliability of the structural components. This work employs an ultrasonic vibration fatigue testing system to investigate the biaxial fatigue failure mechanism of the welded joints. The results revealed that under uniaxial loading conditions, the propensity for fatigue failure in plate specimens was predominantly observed at the specimen surface. Regardless of whether under uniaxial or biaxial loading, the initiation of fatigue cracks in cruciform joints was consistently traced back to unfused flaws, which were primarily located at the interface between the solder and the base material. Concurrently, it was noted that the fatigue strength of cruciform joints under biaxial loading was merely 44.4% of that under uniaxial loading. The geometric peculiarities of the unfused defects led to severe stress concentrations, which significantly reduced the fatigue life of the material under biaxial loading conditions. Full article
