Evolution of the defect structure of the cascade region (CR) formed under irradiation in fcc materials, both with a large stacking fault energy (SFE) and with a small one, has been studied by use of the molecular dynamics technique (MDT). It is shown that when a 1 keV cascade is ...
(fcc) metals was analyzed based on the direct competition between twinning partial dislocation nucleation and trailing partial dislocation nucleation, with which the twinnability of fcc metals can be simply expressed as function of the stacking-fault energy, the unstable sta 分析面孔集中立方体fcc (的...
The plastic deformation of aluminum (Al) is based on this mechanism, and twinning is difficult to initiate due to its high stacking fault energy21. The universal fcc structure and the dislocation-slip-based plastic deformation mechanism led to our material design of hierarchical nanostructured Al ...
Otsuka et al.6 and Gu et al.8 suggested that for obtaining a large RS, the alloying design in the Fe-Mn-Si-based steels should satisfy the following two main criteria: (1) the stacking fault energy (SFE) should be as low as possible to facilitate the SIEM transformation; and (2) ...

Generalized stacking fault energy, ideal strength and twinnability of dilute Mg-based alloys: A first-principles study of shear deformation In an effort to establish a scientific foundation for the computational development of advanced Mg-based alloys, a systematic study of the generalized stac... ...
Thermoelectric (TE) energy conversion is one of the best alternative renewable energy technologies for recovery of the energy in waste heat. A thermoelectric module has several unique advantages that include low maintenance cost, absence of moving parts and environmental cleanliness [1]. Since the ...

High-pressure torsion of pure metals: Influence of atomic bond parameters and stacking fault energy on grain size and correlation with hardness. Acta Mater. 59, 6831–6836 (2011). 19. Edalati, K. & Horita, Z. Correlations between hardness and atomic bond parameters of pure metals and semi...
energy boundaries of the recrystallized grains, and the grain growth in Mg-Zn-Ca was much more suppressed than that in the Mg-Zn and Mg-Ca binary alloys. They concluded that the co-segregation significantly reduced the boundary mobility probably by decreasing grain boundary energy, leading to ...
