Coarse-grained and ultrafine-grained titanium high-temperature creep [PDF]

, 2020
The publication describes the study of durability in tensile creep of VT1-0 commercial titanium in its two states - coarse-grained and ultrafine-grained. It is shown that the best temperature for log-term testing is 350°С.

Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

Advanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.

Synergetic enhancement of strength and ductility by heterogeneous architecture in interpenetrating copper and graphene‑copper composite

Materials Letters: X
Metal matrix composites exhibit an obvious decrease in ductility and toughness as strength increases. Inspired by the heterostructure characteristics of biological materials, this study designs a coarse-grained/ultrafine-grained heterostructure. A copper

Ultrafine-grained materials: a personal perspective [PDF]

International Journal of Materials Research, 2007
Abstract The Chinese philosopher Lao Tzu wrote that “a journey of a thousand li begins with a single step”.† My first step on the road to ultrafine-grained materials occurred on 5 May, 1989, when I boarded a plane in Los Angeles on the way to Ufa via Copenhagen and Moscow.

Ethical Precision in Nanoscale Brain Interfacing

Advanced Science, EarlyView.
As brain interfaces approach the nanoscale, precision no longer only measures—it knows, predicts, and potentially reshapes the mind. This work argues that traditional ethics fails under such conditions and proposes a shift toward continuous, operation‐based governance using the recovery–discovery framework to track, constrain, and responsibly steer ...

Accumulative Roll Bonding of Aluminum/Stainless Steel Sheets [PDF]

Journal of Ultrafine Grained and Nanostructured Materials, 2017
An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times.

Unifying Composition and Process Design: A Heterogeneous Graph Neural Network for Discovering High‐Performance Cu Alloys

Advanced Science, EarlyView.
By overcoming the fixed‐path limitations of conventional machine learning, a heterogeneous graph neural network fundamentally reconstructs material data representation. Integrating variable processing sequences with intrinsic elemental features, this framework enables exploratory optimization across high‐dimensional spaces.

Dual d–p hybridization in Ternary PtGaGe Enables Concurrent Activity and Stability Enhancement for Alkaline Oxygen Reduction

Angewandte Chemie, EarlyView.
A unique dual d–p orbital hybridization strategy was established in a ternary PtGaGe alloy catalyst to overcome the longstanding activity–stability trade‐off in oxygen reduction reaction (ORR). Synergistic hybridization between Ga/Ge p orbitals and Pt d orbitals modulates the Pt electronic structure, optimizes oxygen intermediates adsorption, and ...
