Dislocation-ledge coupling governs semicoherent precipitate growth
Jin-Yu Zhang, Juan Du, Lin Yang +3
The paper investigates how dense interfacial dislocation networks move and reorganize during semicoherent precipitate growth, using in situ TEM, O‑lattice analysis, and 3D phase‑fi…
Machine-learned atomistic simulations reveal the basis of hydrogen-induced crack-plane transition in alpha-Fe
Jiaqin Xu, Zhiqiang Zhao, Kazuma Ito +4
Hydrogen-related fracture in body-centered cubic Fe and ferritic steels often appears as transgranular quasi-cleavage rather than purely intergranular failure, especially at low to…
Negative Strain-Rate Sensitivity in Metallic Glasses Driven by Rejuvenation-Relaxation Competition: Kinetic Monte Carlo Simulations and a Minimal Effective Model
Tomoaki Niiyama, Akio Ishii, Takahiro Hatano +2
When strain-rate sensitivity (SRS) is negative in metallic glasses, the material becomes weaker as the deformation rate increases, leading to accelerated plastic deformation and, e…
Dual Role of Nb in Defect-Mediated Strength and Ductility of γ-TiAl Alloys
Zhiqiang Zhao, Siyao Shuang, Kepeng Ouyang +8
The origin of the superior high-temperature strength of γ-TiAl with high Nb addition remains highly controversial, largely due to the unclear role of Nb atoms. Using large-scale h…
