Grain refinement of Mg-3Y alloy using Mg-10Al2Y master alloy

Journal of Rare Earths, 2021
Abstract The as-extruded Mg-10Al2Y master alloy was chosen as a novel grain refiner for as-cast Mg-3Y alloy. Contrast samples of cast Mg-3Y alloy added with pure Al and Mg-Zr master alloy grain refiners were prepared under the same conditions. In this study, the influence of addition amounts of Al2Y and holding time on grain refinement efficiency as ...

Suppressing atomic diffusion with the Schwarz crystal structure in supersaturated Al–Mg alloys

Science, 2021
Locking structure to high temperature Because of atomic diffusion, metal alloys with nanometer-sized crystal grains do not retain their structure at high temperature. Xu et al.

Surface Alloying of Mg Alloys After Surface Nanocrystallization

Journal of Nanoscience and Nanotechnology, 2008
Surface nanocrystallization using a surface mechanical attrition treatment effectively activates the surface of magnesium alloys due to the increase in grain boundary diffusion channels. As a result, the temperature of subsequent surface alloying treatment of pure Mg and AZ91 alloy can be reduced from 430 °C to 380 °C.

Investigating the Use of Mg-3Pb Alloy for Cathodic Protection of Mg Alloys

ECS Meeting Abstracts, 2023
Magnesium alloys possess many interesting properties, including high strength-to-weight ratios, good castability, and excellent biocompatibility. However, its use has been limited because they are also highly reactive and susceptible to corrosion in aqueous environments.

Alloying behaviors of AgMg, AuMg and AgAl alloys

Journal of Physics and Chemistry of Solids, 1974
Abstract An expression of the structure-dependent energy of simple metal-noble metal binary alloy is given on the basis of the pseudopotential method. The energy is expressed as a sum of three parts; a band-structure energy, an electrostatic energy and a repulsive overlap energy, each of which is characterized by the usual long-range and short-range ...

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

Thermochemical investigation of Sm–Mg alloys

Calphad, 2014
Abstract 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, 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.
