Special Issue Information

Dear Colleagues,

High-performance steel, known for its exceptional mechanical properties, finds wide-ranging applications in fields such as automotive, aerospace, construction, and energy. However, traditional design and manufacturing methods often fail to fully exploit the potential of high-performance steel and meet the requirements of steel structural components in complex engineering environments. In recent years, significant progress has been made in the design and manufacturing of steels. New manufacturing techniques enable high-end forming and service performance on steel and its structural components, meeting the high demands for properties such as friction, wear, and fatigue under extreme operating conditions. Therefore, innovative efforts are urgently needed at various steel processing stages. By developing green and efficient processing technologies to replace traditional lengthy processes, carbon emissions can be reduced. We also hope that steel possesses long-lasting performance and high structural integrity.

This Special Issue aims to provide a platform for researchers to share their latest findings and innovative advancements in the field of high-performance steels. We welcome submissions from various disciplines, including but not limited to the following: understanding of the microstructure and properties of high-performance steel, maximization and optimization of the mechanical properties of high-performance steels through tailoring the microstructure, synergistic design of novel microstructure achieving high-performance of steels, manufacturing and enhancement of high-performance/multi-functional components, green and efficient processing technologies, as well as wear resistance, fatigue resistance, creep, and damage resistance of steel.

Abstract
Press-hardened steels (PHS), as an alternative to traditional steels and aluminum alloys, combine great mechanical performance with low manufacturing costs. PHS are martensitic steels with ultimate tensile strength (UTS) up to 2000 MPa. These steels are commonly coated with zinc-based coatings (PHS GI) [...] Read more.
Press-hardened steels (PHS), as an alternative to traditional steels and aluminum alloys, combine great mechanical performance with low manufacturing costs. PHS are martensitic steels with ultimate tensile strength (UTS) up to 2000 MPa. These steels are commonly coated with zinc-based coatings (PHS GI) consisting of multiple Zn–Fe phases to enhance corrosion resistance. However, similar to all high-strength steels, PHS are known for their elevated susceptibility to hydrogen embrittlement (HE). Absorption of atomic hydrogen into the steel lattice can lead to a transition from a ductile to a brittle fracture mechanism and decrease the stress necessary for fracture initiation. This review examines the microstructure of PHS GI with a focus on how the manufacturing process influences key parameters of the coating. The material’s susceptibility to HE is discussed in the following sections, along with the potential for hydrogen introduction through corrosion in atmospheric environments. The relationship between the content of hydrogen and its effects on fracture behavior is discussed, along with the corrosion behavior of PHS GI. The potential areas for future research and development of PHS GI with increased HE resistance are proposed. Full article
