High Energy Micro-Arc Alloying of Mg-RE on AZ31 Mg Alloy
Advanced Materials Research, 2011Mg-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

Thermochemical investigation of Sm–Mg alloys
Calphad, 2014Abstract The paper focuses on the thermochemical behaviour of the binary Sm–Mg alloys. The enthalpies of formation of the Sm–Mg intermetallic compounds have been determined at 300 K by high temperature direct synthesis calorimetry. The following results in kJ/mole of atoms are reported: −18.5±2 (SmMg), −16.0±2 (SmMg 2 ), −12.0±2 (SmMg 3 ), −8.5±2 ...

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.

Alloy solid solution strengthening of Mg alloys: Valence effect
physica status solidi (b), 2012AbstractAb initio density functional theory (DFT) calculations were carried out to investigate alloy solid solution strengthening of hexagonal close packed (HCP) Mg. The binary solid solution Mg–X base alloys (X = Gd, Nd, Ce, Bi, In, and Sn) were examined to identify a possible valence effect on the solution strengthening in terms of electronic density

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 ...

Applications of thermodynamic calculations to Mg alloy design: Mg–Sn based alloy development
International Journal of Materials Research, 2007Abstract Recently an Mg – Sn based alloy system has been investigated actively in order to develop new magnesium alloys which have a stable structure and good mechanical properties at high temperatures. Thermodynamic modeling of the Mg – Al – Mn – Sb – Si – Sn – Zn system was performed based on available thermodynamic, phase equilibria ...

Mg-Rich Light Alloys Synthesised by Mechanical Alloying
Key Engineering Materials, 2002In this work, MgxTi1-x (x = 18, 50 and 95 at.%) and Mg88Ti4Si7 alloys were synthesised by mechanical alloying. Phase transformations occurring in the samples as a function of milling time and during subsequent heating were studied by means of x-ray diffraction, scanning electron microscopy, differential scanning calorimetry and electron probe ...

Understanding the Corrosion of Mg and Mg Alloys
2018This article summarizes current, fundamental knowledge of the corrosion of magnesium, and highlights some latest developments. Mg is a most reactive metal. The high available reaction energy, and because the simultaneous exchange of two electrons is forbidden by quantum mechanics, means that there is a highly reactive intermediate that can chemically ...

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 ...

Precipitation Processes in Mg–Th, Mg–Th–Mn, Mg–Mn, and Mg–Zr Alloys
Metal Science Journal, 1972Abstract A study has been made of precipitation processes in selected magnesium-base alloys by means of electron microscopy. The principal part of the investigation was concerned with the effect of manganese precipitation in a Mg-Th alloy. It is shown that the sequence of precipitation in a Mg–2.0percnt; Th–1.0% Mn alloy (HM21) is not as complex as ...
