Influence of trace As content on the microstructure and corrosion behavior of the AZ91 alloy in different metallurgical conditions

Journal of Magnesium and Alloys, 2020
The influence of trace As content (0.04, 0.05, 0.06 wt%) on the microstructure and corrosion behavior of AZ91 alloy in different metallurgical conditions (as-cast, as-quenched, peak-aged) was firstly investigated.

Study of Influence of Aluminum Nitride Nanoparticles on the Structure, Phase Composition and Mechanical Properties of AZ91 Alloy

Metals, 2022
In this work, magnesium-based composites were obtained by shock-wave compaction of a powder mixture of Mg-5 wt.% AlN at a shock-wave pressure of 2 GPa. Their microstructure was investigated and the phase composition was determined, from which it follows ...

Development and Characterization of AZ91 Magnesium Alloy Reinforced with Ti Wires. [PDF]

Materials (Basel)
Lightweight metals are increasingly used in biomedical engineering, and can be found in orthopaedics (screws, implants), stomatology, cardiology (stents) and as scaffolds. Magnesium alloys have a low density (1.74 g/cm3), which is very close to that of bone (1.75 g/cm3), as well as high biocompatibility, and are biodegradable.

Effect of solution annealing on microstructures and corrosion behavior of wire and arc additive manufactured AZ91 magnesium alloy in sodium chloride solution

Journal of Materials Research and Technology, 2022
Recently, wire and arc additive manufacturing (WAAM) technique has been used to fabricate the Mg alloy parts, and the solution annealing was generally employed to eliminate the residual stress and homogenize the microstructure of WAAM Mg alloy.

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 %).

Corrosion Resistance of AZ91 Magnesium Alloy with Pulse Electrodeposited Ni-SiC Nanocomposite Coating [PDF]

Журнал нано- та електронної фізики, 2012
Magnesium and its alloys are the lightest of the structural metals, which makes them one of the most promising materials to minimize vehicle weight, but poor surface properties restrict the application of these alloys. In this paper, Ni-SiC nanocomposite

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 ...
