Ductile and brittle crack-tip response in equimolar refractory high-entropy alloys
Xiaoqing Li, Wei Li, Douglas L. Irving +3
Understanding the strengthening and deformation mechanisms in refractory high-entropy alloys (HEAs), proposed as new high-temperature material, is required for improving their typi…
Dissociated dislocation-mediated carbon transport and diffusion in austenitic iron
Ruiwen Xie, Song Lu, Wei Li +2
Dislocation-solute interaction plays fundamental roles in mechanical properties of alloys. Here, we disclose the essential features of dislocation-carbon interaction in austenitic…
Theory of transformation-mediated twinning
Song Lu, Xun Sun, Xianghai An +4
High-density and nanosized deformation twins in face-centered cubic (fcc)materials can effectively improve the combination of strength and ductility. However, the microscopic dislo…
Quantum mechanics basis of quality control in hard metals
Ruiwen Xie, Raquel Lizárragaa, David Linder +6
Non-destructive and reliable quality control methods are a key aspect to designing, developing and manufacturing new materials for industrial applications and new technologies. The…
First-Principles prediction of the deformation modes in austenitic Fe-Cr-Ni alloys
Wei Li, Song Lu, Dongyoo Kim +3
First-principles alloy theory is used to establish the -surface of Fe-Cr-Ni alloys as function of chemical composition and temperature. The theoretical stacking fault energy (SF…
Effect of interstitial-driven lattice expansion on the stacking fault energy in austenitic steels
Song Lu, Wei Li, Se Kyun Kwon +4
Interstitials (carbon and nitrogen) are crucial alloying elements for optimizing the mechanical performance of the twinning-induced plasticity (TWIP) steels in terms of the stackin…
