Understanding the High Creep Resistance of MRI 230D Magnesium Alloy through Nanoindentation and Atom Probe Tomography

Metals, 2021
Due to their low density, magnesium alloys are very appealing for light-weight constructions. However, the use of the most common magnesium alloy, AZ91 (Mg 9 wt.% Al, 1 wt.% Zn), is limited to temperatures below 150 °C due to creep failure.

Creep Behavior of AZ91 Magnesium Alloy

Procedia Engineering, 2013
AbstractEffects of intermetallic phases on the creep behavior of AZ91 magnesium alloy have been studied. Thermally stable intermetallic phases such as Mg2Si and Mg3Sb2 are introduced deliberately in AZ91 alloy by the adding Si and Sb (0.5% Si, 0.5% Sb and 0.5% Si+0.2% Sb, all are in wt %).

Crack source and propagation of AZ91-0.9Gd alloy

Journal of Materials Research and Technology, 2022
Formation process of main compounds in AZ91-0.9Gd alloy was studied, and main crack sources and fracture mechanism were analyzed. Experimental results show that AZ91-0.9Gd alloy is mainly composed of α-Mg, Mg17Al12, bulk Al2Gd compound and a small amount of Al–Mn-Gd ternary compound. Formation sequence is α-Mg, Al2Gd, Mg17Al12 and Al–Mn-Gd. During load

Effect of carrier gases on the entrainment defects within AZ91 alloy castings

Journal of Magnesium and Alloys, 2022
An entrainment defect (also known as a double oxide film defect or bifilm) acts a void containing an entrapped gas when submerged into a light-alloy melt, thus reducing the quality and reproducibility of the final castings. Previous publications, carried

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

Microstructure of the Bonding Zone Between AZ91 and AlSi17 Formed by Compound Casting

Archives of Foundry Engineering, 2017
This paper discusses the joining of AZ91 magnesium alloy with AlSi17 aluminium alloy by compound casting. Molten AZ91 was cast at 650°C onto a solid AlSi17 insert placed in a steel mould under normal atmospheric conditions. Before casting, the mould with

Laser Metal Deposition of Aluminum Alloys 7075 and 5083 with the Addition of Volatile Alloying Elements through Powder Blending

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.
