Impact of Aging Conditions and Glass Reinforcement on Microstructural and Mechanical Features of AZ91 Composites

Engineering Reports, Volume 7, Issue 12, December 2025.
FSBE combined with BG reinforcement produced a highly refined and stabilized microstructure through dynamic recrystallization and Zener pinning. BG particles acted as potent heterogeneous nucleation sites, accelerating β‐Mg17Al12 precipitation and enhancing precipitation kinetics. Aging for 12 h maximized mechanical performance, with yield strength and

Strengthening/weakening effect of graphene orientation angle on mechanical properties of AZ91 magnesium matrix composites

Journal of Magnesium and Alloys
Graphene, as the reinforcing phase of magnesium matrix composites, can effectively improve the material strength, elastic modulus, and other properties. However, the random distribution of graphene in the matrix (i.e., random orientation angle) leads to ...

Influence of annealing and spheroidizing treatment on microstructure and mechanical properties of AZ91 magnesium alloy [PDF]

China Foundry, 2013
The low-strength and high-brittleness of AZ91 cast magnesium alloy mainly result from the coarse divorced eutectic phase. To solve these problems, the annealing treatment of AZ91 cast magnesium alloy was carried out at 415 ℃ and held for 24 h in this ...

Grain refinement of magnesium alloy AZ91E

, 2012
Spark Plasma Sintering (SPS) process has been used to develop a novel grain refiner Al-SiC master alloy for AZ91E Mg alloys. When the Al-SiC master alloy was added to molten AZ91E alloy, the Al matrix melted and allowed the SiC particles to distribute homogeneously throughout the molten AZ91E alloy.
