Microstructure and mechanical properties of AZ61 Mg alloy prepared by multi directional forging

Transactions of Nonferrous Metals Society of China, 2010
Abstract AZ61Mg alloy was multi directionally forged (MDFed) during decreasing temperature condition from 643 K to 483 K at a true strain rate of 3×10−3 s−1 up to cumulative strain of ΣΔe=4.0 at maximum. A pass strain of Δe=0.8 was employed. While average grain size decreased gradually with increasing cumulative strain, the evolution of fine-grained ...

Prevalence and Patterns of Non‐Medical Gabapentinoid Use in a General Population Sample: Findings From the Australian National Drug Strategy Household Survey

Drug and Alcohol Review, Volume 45, Issue 4, May 2026.
ABSTRACT Introduction Gabapentinoid prescribing and related harms are increasing internationally, yet population‐level evidence on non‐medical use in Australia is lacking. This study estimated the prevalence and correlates of past‐year non‐medical gabapentinoid use and examined temporal trends. Methods Data were pooled from the 2016, 2019 and 2022–2023

Miniaturised experimental simulation and combined modelling of open-die forging of Ti-6Al-4V titanium alloy

Journal of Materials Research and Technology
This study demonstrates the application of a new experimental technique for laboratory-scale simulation of the open-die forging process, known as cogging, an intermediate hot-working process necessary to design an optimised microstructure in the advanced

An adaptive, fully implicit multigrid phase-field model for the quantitative simulation of non-isothermal binary alloy solidification [PDF]

, 2008
Using state-of-the-art numerical techniques, such as mesh adaptivity, implicit time-stepping and a non-linear multi-grid solver, the phase-field equations for the non-isothermal solidification of a dilute binary alloy have been solved.

Evolution of crop phenotypic spaces through domestication

New Phytologist, Volume 250, Issue 3, Page 1948-1963, May 2026.
Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11–57 qualitative and quantitative traits in 13 species, either unique or shared between species, and established a framework for cross‐species comparisons. Our results revealed

Effect of Surface Treatment of Multi-Directionally Forged (MDF) Titanium Implant on Bone Response

Metals, 2019
Multi-directional forging (MDFing) of titanium drastically improved its mechanical properties due to the evolution of an ultrafine-grained structure. Forging strain was repeatedly applied while changing the forging axis during MDFing.
