Achieving Superior Mechanical Properties for Al‐Zn‐Mg‐Cu Alloy by Coupling Design of Powder Press‐Forming, Deformation, and Aging

open access: yesRare Metals, EarlyView.
ABSTRACT Enhancing the strength of 7000 series high‐strength Al alloys remains a critical challenge to meet the demands of increasingly demanding service environments. In this study, a novel approach is proposed for developing high‐performance Al alloys through a combination of powder mechanical alloying, powder press‐forming, rolling deformation, and ...

Multi‐Functional S‐HA/ASTA NPs Coating on Biodegradable ZE21B Alloy for Cerebrovascular Applications

open access: yesRare Metals, EarlyView.
ABSTRACT Magnesium (Mg) and its alloys have attracted extensive attention of researchers in the field of cerebrovascular implants due to their good mechanical properties and biosafety. However, rapid degradation and delayed endothelialization pose challenges. To address these issues, this study introduces a multifunctional composite coating.
