Metallography of Mg Alloys

2019
Processing and composition determine microstructural properties. To reveal the microstructure, the metallographic investigation is a commonly used method, and therefore, it is a crucial part in the characterization of metals and alloys. Choosing incorrect preparation steps will lead to artefacts and misleading conclusions due to the compositional ...

High Energy Micro-Arc Alloying of Mg-RE on AZ31 Mg Alloy

Advanced Materials Research, 2011
Mg-RE electrode was used for deposition of micro-arc coatings on AZ31 magnesium alloy upon variation in there different processing parameters(high, low and middle pulsed discharges). Mass transfer trends from electrode to substrate and microstructure of Mg-RE coating on AZ31 substrate were observed. Characterization has been performed by using scanning

The Microstructures of As-Cast Mg-Zr and Mg-Mn Alloys

Materials Science Forum, 2005
The as-cast microstructures of two dilute Mg-Zr and three dilute Mg-Mn alloys were studied using optical microscopy and scanning electron microscopy, including EDX analysis. The results show that the as-cast microstructure of the Mg-Zr alloys was composed of non-dendritic, equiaxed Mg grains, with a few Zr particles within the Mg grains and along grain

Texture Development in Pure Mg and Mg Alloy AZ31

Materials Science Forum, 2005
Texture evolution in pure Mg and Mg alloy AZ31 during deformation and annealing was investigated. The poor low temperature ductility can be attributed to both, insufficient shear systems and unfavorable deformation geometry. Static recrystallization was shown to proceed discontinuously despite little texture change.

Bonding of AZ91D Mg Alloy and Al Metal with Mg-Al Eutectic Alloy and its Application in Al Coating on AZ91D Mg Alloy

Materials Science Forum, 2009
AZ91D magnesium alloy and Al metal were bonded successfully at 450 oC with load of 25 or 31 MPa by using Mg-Al eutectic alloy as the solder in atmosphere. The microstructure of the AZ91D/Al joints was characterized by SEM equipped with EDS, and the bond strength was measured through three-point bending test.

Mechanical alloying and milling of Al–Mg alloys

Journal of Alloys and Compounds, 2009
Abstract Solid solubility extension of Mg in Al was achieved for the binary Al–Mg system in the range of 10–40 at.% Mg by mechanical alloying of elemental powder mixtures and by mechanical milling of pre-alloyed ingots. No indication for the formation of the equilibrium phases (β-Al3Mg2 and γ-Al12Mg17) after milling was observed.

Mg Based Alloys Obtained by Mechanical Alloying

Materials Science Forum, 1998
In the present work, we studied the production of magnesium alloys, of stoichiometry 2Mg + Ni, by mechanical alloying (MA) and the behavior of the alloys under hydrogen in a Sievert's type apparatus. The elemental powders were milled under argon atmosphere in a Spex 8000 high energy ball mill.

Corrosion, Surface Modification, and Biocompatibility of Mg and Mg Alloys

2011
This manuscript summarizes recent studies on the corrosion behavior of Mg and Mg alloys in simulated biological environments, as well as interactions between corroding Mg (alloy) surfaces and cells. The influence of different types of simulated body solutions on the corrosion behavior of Mg is discussed.
