Description Titanium gets some twins Introducing a network of nanotwins is known to improve the properties of face-centered cubic metal alloys. Zhao et al. used gentle compression in liquid nitrogen to introduce a similar network of nanotwins in hexagonal closed-packed titanium. By starting with a titanium that has little oxygen, the twin network can be more easily established. The nanotwinned network improved the yield strength by 50% and ductility by 20% at room temperature. The cryogenic… 
Response to Comment on “Cryoforged nanotwinned titanium with ultrahigh strength and ductility”
We address the three main points of Guo et al. They claim that we should have used the engineering stress versus engineering strain curves to infer the mechanical properties of our nanotwinned
Hierarchical twinning governed by defective twin boundary in metallic materials
Dense networks of deformation twins endow metals and alloys with unprecedented mechanical properties. However, the formation mechanism of these hierarchical twin structures remains under debate,
Effect of Abnormal Grains on the Mechanical Properties of FGH96 Solid-State Diffusion Bonding Joint
The hollow twin-web disk is designed to improve the thrust-to-weight ratio of the aero engine, where the welding joint microstructures determine the disk’s mechanical properties. This study aimed to
In-situ neutron diffraction study of lattice deformation behaviour of commercially pure titanium at cryogenic temperature
Titanium has a significant potential for the cryogenic industrial fields such as aerospace and liquefied gas storage and transportation due to its excellent low temperature properties. To develop and
Microstructure, Texture, and Hardness Evolution of Cold-Rolled High-Purity Ti Sheet During Annealing at 350 °C to 550 °C
The microstructural, textural, and hardness evolution of a cold-rolled high-purity Ti sheet (50 pct reduction in thickness) during isochronal annealing at 350 °C to 550 °C was investigated by jointly
Strengthening mechanism of Ti-W composites with heterogeneous microstructures
Heterogeneous Ti-W metal–metal composites were designed in this study. The effects of W particles on microstructural evolution and strengthening mechanisms were investigated. There was slight
Comment on “Cryoforged nanotwinned titanium with ultrahigh strength and ductility”
We analyze the results of Zhao et al. (Reports, 17 September 2021, p. 1363) with a focus on the mechanical properties and microstructural evolution. We conclude that their results, together with the


Extra strengthening and work hardening in gradient nanotwinned metals
This work indicates that simultaneous enhancement in strength and work hardening can be achieved by solely increasing the structural gradient in pure Cu, and provides insights into combining structural gradients at different length scales in order to push forward the strength limit of materials.
Nanotwinned diamond with unprecedented hardness and stability
The direct synthesis of nt-diamond with an average twin thickness of ∼5 nm is reported, using a precursor of onion carbon nanoparticles at high pressure and high temperature, and the observation of a new monoclinic crystalline form of diamond coexisting with nt -diamond is observed.
Nanotwinned and hierarchical nanotwinned metals: a review of experimental, computational and theoretical efforts
The recent studies on nanotwinned (NT) and hierarchical nanotwinned (HNT) face-centered cubic (FCC) metals are presented in this review. The HNT structures have been supposed as a kind of novel
Revealing the Maximum Strength in Nanotwinned Copper
The maximum strength of nanotwinned copper samples with different twin thicknesses is investigated, finding that the strength increases with decreasing twin thickness, reaching a maximum at 15 nanometers, followed by a softening at smaller values that is accompanied by enhanced strain hardening and tensile ductility.
Cryogenic mechanical properties of Ti-6Al-4V alloys with three levels of oxygen content
Tensile, fracture toughness, and high cycle fatigue tests were done at 293, 77, and 4 K for Ti-6Al-4V alloys with three levels of oxygen content. The alloys were investigated both in as-forged
