Journal ArticleDOI
Structural and elastic properties of cubic and hexagonal TiN and AlN from first-principles calculations
Aijun Wang,Shun Li Shang,Yong Du,Yi Kong,Lijun Zhang,Lijun Zhang,Li Chen,Dongdong Zhao,Zi Kui Liu +8 more
TL;DR: In this article, the structural and elastic properties of polycrystalline aggregates including bulk modulus (B), shear modulus, Poisson's ratio, and anisotropy ratio are determined and compared with the experimental and theoretical results available in the literature.
Journal ArticleDOI
Segregation of Mg, Cu and their effects on the strength of Al Σ5 (210)[001] symmetrical tilt grain boundary
TL;DR: In this article, the authors investigated the Mg and Cu segregation behavior at the symmetrical tilt grain boundary (STGB) in Al and found that both mg and cu have a large driving force to segregate to Al grain boundaries, with Mg preferentially segregating at symmetric core sites and Cu at interstitial hollow sites at the grain boundary.
Journal ArticleDOI
An overview on phase equilibria and thermodynamic modeling in multicomponent Al alloys: Focusing on the Al–Cu–Fe–Mg–Mn–Ni–Si–Zn system
TL;DR: In this article, a review of phase diagram and thermodynamics of technologically important Al alloys focusing on the Al-Cu-Fe-Mg-Mn-Ni-Si system is presented.
Journal ArticleDOI
Effects of Cu and Al on the crystal structure and composition of η (MgZn2) phase in over-aged Al–Zn–Mg–Cu alloys
TL;DR: In this article, the effects of Cu and Al substitution on the diffraction characteristics of the MgZn2 phase were investigated by high resolution transmission electron microscopy, aberration corrected scanning transmission electron microscope, selected election diffraction pattern simulations, and first-principles calculations.
Journal ArticleDOI
Revealing the strengthening and toughening mechanisms of Al-CuO composite fabricated via in-situ solid-state reaction
TL;DR: In this paper, a shift-speed ball-milling (SSBM) of Al-5 wt.% CuO powders is reported to achieve high tensile strength and fracture elongation.
