Journal ArticleDOI
Origin of dramatic oxygen solute strengthening effect in titanium
Qian Yu,Qian Yu,Liang Qi,Tomohito Tsuru,Rachel Traylor,D. Rugg,J. W. Morris,Mark Asta,Daryl C. Chrzan,Andrew M. Minor,Andrew M. Minor +10 more
TL;DR: It is reported that the intense hardening effect of dilute oxygen solutes in pure α-Ti is due to the interaction between oxygen and the core of screw dislocations that mainly glide on prismatic planes, establishing a highly effective mechanism for strengthening by interstitial solutes.
Journal ArticleDOI
Anisotropic effects in elastic and incipient plastic deformation under (001), (110), and (111) nanoindentation of Al and Cu
Tomohito Tsuru,Yoji Shibutani +1 more
TL;DR: In this paper, the authors compared two materials, single-crystalline Al and Cu, focusing on the large difference between their anisotropic properties, and found that the indent load-depth behavior of Al during elastic deformation exhibits slight anisotropy, while that of Cu varies greatly according to the indentation axis.
Journal ArticleDOI
Effect of solute atoms on dislocation motion in Mg: An electronic structure perspective
Tomohito Tsuru,Daryl C. Chrzan +1 more
TL;DR: The electronic structure associated with, and the energy barriers to dislocation cross-slip, are computed and it is argued that Y, Ca, Ti, and Zr should interact strongly with the studied dislocation, and thereby decrease the dislocation slip anisotropy in the alloy.
Journal ArticleDOI
Interfacial segregation and fracture in Mg-based binary alloys: Experimental and first-principles perspective
Tomohito Tsuru,Tomohito Tsuru,Hidetoshi Somekawa,Hidetoshi Somekawa,Daryl C. Chrzan,Daryl C. Chrzan +5 more
TL;DR: In this paper, the effect of solute elements on interfacial segregation and fracture in Mg alloys was investigated by first-principles density functional theory calculations in conjunction with both experiment and interfacial fracture mechanics.
Journal ArticleDOI
Solution softening in magnesium alloys: the effect of solid solutions on the dislocation core structure and nonbasal slip.
TL;DR: In this study, a mechanism for enhancing the ductility of magnesium alloys has been pursued using the atomistic method and Yttrium was found to have an anomalous influence on the solution softening owing to a reduction in the GSF energy gradient.
