Twin boundaries (TBs) are ubiquitous interfaces with specific structure in metallic materials.
They possess special interactions with dislocations and the fatigue cracking behaviors are …

Dynamic recrystallization (DRX) often takes place during hot deformation of metallic
materials, which then exerts significant influence on the final microstructures and …

Hydrogen embrittlement (HE) causes engineering alloys to fracture unexpectedly, often at
considerable economic or environmental cost. Inaccurate predictions of component lifetimes …

Fatigue crack initiation in high-angle grain boundaries is often observed experimentally,
however, its mechanism is a subject of controversy. Low cycle fatigue loading has been …

The tensile mechanical properties of a Ni-based superalloy 718 uniformly precharged with≈
90 mass ppm hydrogen were investigated under a wide range of temperatures to shed light …

Fatigue crack nucleation at annealing twin boundaries (TBs) within polycrystal nickel-based
superalloy René 88 DT is investigated with a microstructure-sensitive crystal plasticity (CP) …

Polycrystalline copper specimens were fatigued in strain-controlled regime with high and
low strain amplitude. Stress amplitude, plastic strain amplitude and hysteresis loops were …

The limited understanding of additive manufacturing process-structure–property inter-
relationships raises some concerns regarding the structural reliability, which limits the …

Low-cycle fatigue behaviors of CrCoNi medium entropy alloy with different grain sizes were
investigated. It is found that grain refinement improved deformation homogeneity to delay …

The cyclic plastic deformation of polycrystals leads to the inhomogeneous distribution of the
cyclic plastic strain. The cyclic plastic strain is concentrated in thin bands, called persistent …
