Difference in extrusion temperature dependences of microstructure and mechanical properties between extruded AZ61 and AZ91 alloys

Journal of Magnesium and Alloys, 2023
The effects of extrusion temperature on the microstructure and tensile properties of extruded AZ61 and AZ91 alloys are investigated by subjecting them to hot extrusion at 300 and 400 °C. Although the average grain size of the extruded AZ61 alloy slightly

Microstructures and the improved mechanical properties of AZ91 alloy by incorporating Ti-6Al-4V particles

Journal of Materials Research and Technology, 2023
Magnesium (Mg) based composites are often difficult to achieve the trade-off between strength and ductility. The titanium (Ti) metal particles, which show better wettability and ductility than ceramic particles, are selected as reinforcements to ...

Synergy of Strength and Plasticity in Extruded VZ91K Magnesium Alloy Achieved by Constructing Bimodal Grain Structure via Suppression of PSN‐DRX

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bimodal grain structure (BGS) demonstrates significant potential in synergistically optimizing the strength and plasticity of magnesium alloys. Acquiring the desired BGS consequently became a critical challenge. This study took the Mg‐9Gd‐1Zn‐0.5Zr (wt%, VZ91K) alloy as its subject. From the perspective of BGS formation mechanisms, it suggests

Randomised, Double‐Blinded, Placebo‐Controlled Challenge Test With Single Food Items in Dogs With Atopic Dermatitis and Adverse Food Reactions

Veterinary Dermatology, Volume 37, Issue 2, Page 247-256, April 2026.
ABSTRACT Background Identification of offending foods in dogs with adverse food reactions is usually based on “deterioration” during open food challenges. Objectives To examine the placebo effect during double‐blinded, placebo‐controlled food challenges using a predefined set of criteria for relapse.
