Biodegradable Mg and Mg alloys: Corrosion and biocompatibility
Materials Science and Engineering: B, 2011Abstract This review discusses the current state and challenges in understanding Mg alloy corrosion behavior, in view of use of these materials for biodegradable implants. After the description of some basic and specific aspects of Mg alloy corrosion, the influence of specific biological environments on the corrosion behavior of Mg alloys is ...

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, 2009Abstract 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.

Amorphization of MgZn alloys by mechanical alloying
Materials Science and Engineering: A, 1989Abstract We report for the first time on the synthesis of magnesium-based amorphous alloy powders using mechanical grinding. We synthesize an amorphous powder of the nominal composition Mg 70 Zn 30 . Using X-ray diffraction and differential scanning calorimetry (DSC) we analyse the details of the magnesium reaction as well as the crystallization ...

Sacrificial Cathodic Protection of Mg Alloy AZ31B by an Mg–5Sn Surface Alloy
2019A solid solution Mg–5Sn alloy is evaluated as a sacrificial anode for the cathodic protection of AZ31B. Uncoupled Mg–5Sn is shown to have superior barrier properties and reduced cathodic kinetics relative to AZ31B. The performance as a sacrificial anode was studied in situ with global and local measurements of galvanic coupling between the Mg–5Sn alloy

Mg Based Alloys Obtained by Mechanical Alloying
Materials Science Forum, 1998In 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.

Synthesis of Mg-Ti alloy by mechanical alloying
Journal of Materials Science, 2003Mg-based Mg-Ti binary alloys have been synthesized by mechanical alloying of Mg and Ti powder blends. It was found that mechanical alloying of Mg and Ti results in a nanocrystalline Mg-Ti alloy and an extended solubility of Ti in Mg, due to the favorable size factor and the isomorphous structure of Mg and Ti.

Abstract The roles of rare earth elements on the texture weakening of Mg alloy are critically assessed. Two main roles are (i) the changing of stacking fault energy of Mg and (ii) the enhancement of solute drag of grain boundaries and dislocations.

Corrosion of Mg and Mg alloys for medical applications [PDF]
, 2012 The core of this thesis consists of two published papers and a manuscript submitted for publication, as Chapters 1 to 3. The research in Chapter 1 compared the corrosion of typical Mg alloys (AZ91, ZE41 and Mg2Zn0.2Mn) and high purity (HP) Mg in Hank’s solution at room temperature and in 3% NaCl saturated with Mg(OH2).
