The article discusses the development of a mathematical model for micro scale magnesium calcium 0.8 (MgCa0.8) alloy wire drawing. It says that the boundary elements method (BEM) was applied for the micro-scale model. It notes that the new model can extinguish the problems that can happen with the use of the finite element method (FEM).
Magnesium is found in seawater and brines, as well as in deposits in the earth. Magnesium reserves are highly concentrated in three countries: Russia, China and Korea. In 2013, identified world resources of magnesite totaled 12 billion tones and world reserves of magnesite totaled 2.4 billion tones with China accounting for 21% (500 million tonnes).
Designing lightweight and comfortable automotive vehicles is a primary aim of the industry. Lightweight wheel designs can have a negative effect on the dynamic impact performance of the wheel; therefore, striking a balance between these two factors is a key objective in the design of automotive vehicles. Magnesium alloy wheels were investigated as magnesium alloy has damping performance
The Role of Rare Earth Elements in Structure and Property Control of Magnesium Die Casting Alloys Bakke, P. / Westengen, H. / Minerals, Metals and Materials Society | 2005 print version
Biodegradable metals have been under significant research as promising alternatives to the currently in-use nonbiodegradable materials in the field of supportive medical implants. In this scope, magnesium and its alloys were widely investigated due to their superior biocompatibility over other metals. Most of the research effort in the literature has been focused on assuring the
May 31, 2012· Intergranular corrosion is caused by Microsegregation of impurities and alloying elements on the grains boundaries. The driving force of intergranular corrosion is the difference between the Electrode potentials of the grain boundary and the grain itself, which form a galvanic cell in presence of an electrolyte. If the phases segregated at the grain boundaries have lower value of electrode
RESULTS: The magnesium alloy clip formed much fewer artifacts than the titanium clip, and it was almost absorbed at 6 months postoperative. There were no postoperative compliions and no elevation of constituent elements such as magnesium, calcium, and zinc during the observation period in …
For engineering appliions, magnesium is usually strengthened by alloying mechanisms; it can be alloyed with other alloying elements such as aluminum, zinc, manganese, zirconium and rare earth. Besides the low density, Mg and Mg-based alloys also have other attractive properties, such as an excellent damping capacity and good electromagnetic
0.02% S, Before alloying it. Magnesium and such elements have strong affinity for sulphur and thus scavenge sulphur from the molten alloy as an initial stage for producing S.G Iron. These additions are expensive to increase the cost of S.G Iron produced. used), before nodulising, should be kept low.
Magnesium-aluminum alloys are used where strong, lightweight materials are required, such as in airplanes, missiles and rockets. Cameras, horseshoes, baseball chers'' masks and snowshoes are other items that are made from magnesium alloys. Magnesium oxide (MgO), also known as magnesia, is the second most abundant compound in the earth''s crust.
Magnesium is one of most liberally available metal in nature forming about 2% of earth’s crust. Polylactic acid or Polylactide is a bioplastic. Magnesium-Polylactide composites are a promising new form of biodegradable materials with established good mechanical properties.
conventional magnesium alloy sheets is a major con-tributing factor to this poor formability.[2,3] Small additions of rare-earth (RE) elements have been shown to modify the texture of magnesium sheet after hot rolling, producing weaker texture and an increased split in basal pole orientations.
