Hydrogen embrittlement (HE) occurs as a result of hydrogen atom ingress and causes a significant decrease in plasticity and strength, making it a crucial failure mode in high-strength low-alloy steels. The microstructure...
A good strength-toughness combination is difficult to be obtained in welded joint of low carbon low alloy steel. In this work, a new idea was proposed to improve the strength and toughness of welded joint by strengthenin...
Using Cr-bearing low-alloy steel is an effective preventive measure for marine structures, as it offers superior corrosion resistance when compared to plain carbon steel. However, it remains unclear how quenching and tem...
Understanding the thermal stability of austenite is critical for designing high-performance steels. Grain size is a key factor controlling thermal stability, but the underlying mechanisms remain partially unclear. For in...
Fabricating multi-material metal sheets through heterostructural design has gained significant attention for achieving multi-objective performance optimization. Present fabricated tri-layered steel (TLS) sheets with a 31...
