Engineering design methods based on the assumption of crack growth and the application
of fracture mechanics principles are commonly used in aerospace engineering for the …

The development of steels with a combination of high strength, ductility, and toughness has
been highly desirable for structural applications. Here we achieve high fracture toughness …

The hierarchical martensitic features in ultra-high strength stainless steel (UHSSS),
including the prior austenite grains, martensite packets, blocks and laths with the …

Heterogeneous grain structures were designed in a high Mn steel (Fe28Mn10Al1. 00C), and
the tensile properties and fracture toughness were investigated and compared with those for …

Fatigue properties of high-strength steels become more and more sensitive to inclusions
with enhancing the ultimate tensile strength (UTS) because the inclusions often cause a …

Rapid tempering is a remarkable sustainable and energy-efficient way to modify properties
of as-quenched martensite, particularly its toughness and ductility. In this work, tensile and …

This study presents the effects of the microstructure on the corresponding fracture toughness
of the Ti–5Al–5Mo–5V–1Cr–1Fe (Ti-55511) alloy by undergoing STA (α/β solution treatment …

In this paper, the fracture toughness and impact toughness were systematically studied in
high-strength steels. The results show that the two types of toughness are both the …

The microstructures in the core of CSS-42L bearing steel, including the hierarchical packet-
block-lath martensite, residual austenite (RA) and carbide were tailored by employing …

The fatigue resistance of metallic materials is generally attributed to both strength and
toughness. Unfortunately, these properties are mutually exclusive in most materials …
