Influence of Al–5Ti–1B master alloy addition on the grain size of AZ91 alloy
Journal of Magnesium and Alloys, 2017 The mechanical properties of castings depend on the grain size. There is evidence that titanium and boron (Al–5Ti–1B master alloy) affect the grain size of magnesium alloys. Here, the influence of the addition of 0–1 wt.

The Effects of Rare Earth Pr and Heat Treatment on the Wear Properties of AZ91 Alloy
Crystals, 2018 This paper investigated the influences of Pr addition and heat treatment (T6) on the dry sliding wear behavior of AZ91 alloy. The wear rates and friction coefficients were measured by using a pin-on-disc tribometer under loads of 30, 60 and 90 N at dry ...

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.

Effect of Gadolinium on the Microstructure of Magnesium Alloy AZ91
Archives of Foundry Engineering, 2021 The paper presents the results of research related to the possibility of inoculation of the AZ91 magnesium alloy casted into ceramic moulds by gadolinium. Effects of gadolinium content (0.1–0.6 wt%) on microstructure of the AZ91 alloy under as-cast state were investigated.

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 %).
