Journal ArticleDOI
Perspectives on Titanium Science and Technology
TL;DR: In this paper, the complexity and variety of fundamental phenomena in this material system with a focus on phase transformations and mechanical behaviour are discussed. And the challenges that lie ahead in achieving these goals are delineated.

Additive manufacturing of Ti6Al4V alloy: A review
Shunyu Liu,Yung C. Shin +1 more
TL;DR: In this paper, the recent progress on Ti6Al4V fabricated by three mostly developed additive manufacturing techniques-directed energy deposition (DED), selective laser melting (SLM) and electron beam melting (EBM)-is thoroughly investigated and compared.

Enhanced strength and ductility in a high-entropy alloy via ordered oxygen complexes
Zhifeng Lei,Xiongjun Liu,Yuan Wu,Hui Wang,Suihe Jiang,S. D. Wang,Xidong Hui,Yidong Wu,Baptiste Gault,Paraskevas Kontis,Dierk Raabe,Lin Gu,Qinghua Zhang,Houwen Chen,Hongtao Wang,Jiabin Liu,Ke An,Qiaoshi Zeng,T.G. Nieh,Zhaoping Lu +19 more
TL;DR: It is shown that oxygen can take the form of ordered oxygen complexes, a state in between oxide particles and frequently occurring random interstitials, which lead to unprecedented enhancement in both strength and ductility in compositionally complex solid solutions, the so-called high-entropy alloys (HEAs).
Journal ArticleDOI
A concept for the design of novel superhard coatings
S. Vepřek,S. Reiprich +1 more
TL;DR: In this article, a concept for the design of novel nanocrystalline/amorphous composites is suggested based on recent theoretical and experimental results regarding the appearance of supermodulus phenomena in composition-modulated layered heterostructures and on a simple thermodynamic criterion for segregation in ternary nitride systems.
Journal ArticleDOI
Mechanical properties and deformation mechanisms of a commercially pure titanium
TL;DR: In this article, the mechanical behavior of a commercially pure titanium (CP-Ti) is systematically investigated in quasi-static (Instron, servohydraulic) and dynamic (UCSD's recovery Hopkinson) compression.

Thermally Activated Unpinning of Dislocations from Point Obstacles in Terms of a Non-Equilibrium Transition-State Theory
Werner Frank,R. Frydman +1 more
TL;DR: The wide-spread treatment of thermally activated unpinning of dislocations from point obstacles in terms of the absolute rate theory is criticized in this paper, where doubts are raised about the validity of the assumption that a thermodynamic equilibrium distribution is established between the equilibrium state of a pinned dislocation and its saddle-point configuration.
Journal ArticleDOI
Characterization of recrystallization and grain growth in Ti-7.4 At. Pct Al (cph) and Ti-15.2 At. Pct Mo (bcc) alloys
TL;DR: In this article, the grain size distribution in both alloys is a constant for a given grain size, independent of annealing time and temperature and follows a log normal distribution.

The effect of oxygen on the strength and ductility of polycrystalline vanadium in the range of 4.2 to 400 K
TL;DR: In this paper, the effect of oxygen on the yield stress and ductility of polycrystalline vanadium was investigated for concentrations of 0.004 to 1.25 at, and the dependence of resolved shear stress on temperature and composition was tested against the different interstitial solute strengthening theories.
The relationship between plastic deformation and fracture in alpha titanium.
M. F. Amateau,E. A. Steigerwald +1 more
TL;DR: In this paper, a general correlation was found between fracture energy, grain orientation and crack propagation events in unalloyed titanium containing 0.25 to 0.6% oxygen.

Internal friction and oxygen pair diffusion in α-zirconium
P. G. Fuller,D. R. Miller +1 more
TL;DR: In this paper, a stress-induced diffusion of oxygen atoms in the basal plane of the hcp lattice has been proposed as the only relaxation process capable of producing the observed damping behaviour.
