Currently, no systematic approach exists to simulate the crack initiation and propagation
process in very-high-cycle fatigue including the microstructure sensitivity. A combined crystal …

The high thermal gradients during the laser powder bed fusion (LPBF) process induce an
inhomogeneous microstructure with anisotropic mechanical properties. This study …

Exposure of metals to neutron irradiation results in an increase in the yield strength and a
significant loss of ductility. Irradiation hardening is also closely related to the fracture …

Renowned for the superior mechanical properties and adeptness at cold-forming,
Quenching and Partitioning (QP) steels have gained prominence as a promising candidate …

Zirconium hydride precipitation degrades the fracture toughness of nuclear reactor fuel
cladding tube. Due to the difficulty of experiment, deep understanding on mechanical …

The fatigue crack nucleation mechanism of Ti-2Al-2.5 Zr alloy was investigated using the
coupling method of quasi in-situ tests with crystal plasticity (CP) simulation. The constitutive …

Al-Ce alloys emerge as promising heat-resist aluminum alloys with service temperatures
above 250° C. Here we report the solidification behavior and the microstructure diversity of …

For metallic materials, high-cycle fatigue life is sensitive to underlying microstructure
features including secondary phases, textures, grains morphology, etc. The traditional, data …

A new model of gradient crystal plasticity is developed in which the incompatibility of plastic
deformation field is simultaneously included in two different ways. The first one is well known …

Hydride precipitation in zirconium (Zr) alloys leads to the deterioration of mechanical
properties in key components of nuclear reactors. However, the underlying mechanisms …
