This book was released on 2015 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The low density and high strength to weight ratio of magnesium alloys makes them ideal candidates to replace many of the heavier steel and aluminum alloys currently used in the automotive and other industries. Although cast magnesium alloys components have a long history of use in the automotive industry, the integration of wrought magnesium alloys components has been hindered by a number of factors. Grain refinement through thermomechanical processing offers a possible solution to many of the inherent problems associated with magnesium alloys. This work explores the development of several thermomechanical processing techniques and investigates their impact on the microstructural and mechanical properties of magnesium alloys. In addition to traditional thermomechanical processing, this work includes the development of new severe plastic deformation techniques for the production of fine grain magnesium plate and pipe and develops a procedure by which the thermal microstructural stability of severely plastically deformed microstructures can be assessed.

Download or read book An Investigation Into the Influence of Thermomechanical Processing on Microstructure and Mechanical Properties of High Strength Aluminum Magnesium Alloys written by William Goodwin Speed and published by . This book was released on 1979 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstructures and mechanical properties resulting from thermomechanical processing of high-Magnesium (Mg) content Aluminum-Magnesium (Al-Mg) alloys were investigated in this research. Warm rolling processes, intended to refine both grain size and second phase Al3Mg2 (beta) particle size, were conducted for alloy compositions of 10.2 weight % Mg, 10.2 weight % Mg plus 0.5 weight % copper (Cu) and 12.1 weight % Mg. Solution treatment, hot upset forging, resolutioning and rapid cooling provided initial microstructural homogenization. Subsequent warm rolling was employed to refine the microstructure. The effect of warm rolling parameters of beta particle size and distribution was of particular concern. By warm rolling an alloy containing 10.2 % Mg plus 0.5 % Cu at 250 C, an ultimate tensile strength of 565 MPa (82000 psi), with 11.5 % elongation, was achieved with the added advantage of a strength to density ratio higher than present equivalent-strength alloys, such as 7075-T6.

Available in PDF, EPUB and Kindle. Book excerpt: Volume is indexed by Thomson Reuters CPCI-S (WoS). Magnesium, with its very rich reserves within the Earth, is an important engineering material, but has not yet been fully developed and utilized. Given its low density, magnesium has a higher specific strength and stiffness than many other engineering materials: including aluminum, steel and polymer-based composites. Magnesium also offers other attractive properties: such as a high damping capacity, electromagnetic shielding, dimensional stability, and good machinability and recyclability. As a relatively new structural material, magnesium and its alloys have demonstrated a significant potential for applications in many industries: including automobile, 3C (computer, communication and consumer) products, transportation, power-tools/equipment and new energy sources.

This book was released on 1980 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was the development of a thermomechanical procedure to process Aluminum-Magnesium alloys and testing effects of alloying additions on these alloys. Magnesium contents of eight and ten weight percent and the alloying effects of copper and manganese were studied. Microstructures and mechanical properties at six warm rolling temperatures located above and below the solvus line of these alloys were examined. Ultimate tensile strengths in excess of 680 MPa (99 KSI) were obtained. Microstructural evidence indicated that the precipitation of the 'beta' intermetallic phase was one of the most important mechanisms in controlling the strength of the alloy. Furthermore, precipitation is so rapid at higher temperatures that it becomes the strongest force within the microstructure and its presence prevents any possible recrystallization of the alloy. However, when the temperature exceeds the solvus temperature for the alloy, recrystallization does occur with large losses in both yield and ultimate tensile strength. (Author).
Download or read book High Strength Aluminum Magnesium Alloys Thermomechanical Processing Microstructure and Tensile Mechanical Properties written by Raymond Arthur Grandon and published by . This book was released on 1979 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstructures and mechanical properties of thermomechanically processed Aluminum-Magnesium alloys were investigated in this research. Magnesium content of the alloys ranged from 7 to 12 weight percent and an alloy containing 10 percent Mg and 0.5 percent Cu was also examined. Thermomechanical processing treatments involved solution treatment followed by warm isothermal rolling. Temperature for this warm rolling was typically 300 C, and this is below the solvus temperature for the alloy. Such processing results in a fine dispersion of the intermetallic compound Al3Mg2 (beta) in a solid solution matrix. Typical mechanical properties are an ultimate tensile strength of 520 Mpa (75000 psi), with 12 percent elongation to fracture. Such a material may be further cold worked to ultimate tensile strengths of 620 Mpa (90000 psi), with 6 percent elongation to fracture. Dynamic recrystallization is necessary to achieve a uniform dispersion of the intermetallic in subsequent processing. (Author).
Download or read book Processing and Characterization of Magnesium Based Materials written by Domonkos Tolnai and published by MDPI. This book was released on 2021-08-31 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to their lightweight and high specific strength, Mg-based alloys are considered as substitutes to their heavier counterparts in applications in which corrosion is non-relevant and weight saving is of importance. Furthermore, due to the biocompatibility of Mg, some alloys with controlled corrosion rates are used as degradable implant materials in the medical sector. The typical processing route of Mg parts incorporates a casting step and, subsequently, a thermo–mechanical treatment. In order to achieve the desired macroscopic properties and thus fulfill the service requirements, thorough knowledge of the relationship between the microstructure, the processing steps, and the resulting property profile is necessary. This Special Issue covers in situ and ex situ experimental and computational investigations of the behavior under thermo–mechanical load of Mg-based alloys utilizing modern characterization and simulation techniques. The papers cover investigations on the effect of rare earth additions on the mechanical properties of different Mg alloys, including the effect of long-period stacking-ordered (LPSO) structures, and the experimental and computational investigation of the effect of different processing routes.

Available in PDF, EPUB and Kindle. Book excerpt: Magnesium is the lightest of all the metals and the sixth most abundant on Earth. Magnesium is ductile and the most machinable of all the metals. Magnesium alloy developments have traditionally been driven by requirements for lightweight materials to operate under increasingly demanding conditions (magnesium alloy castings, wrought products, powder metallurgy components, office equipment, nuclear applications, flares, sacrificial anodes for the protection of other metals, flash photography and tools). The biggest potential market for magnesium alloys is in the automotive industry. In recent years new magnesium alloys have demonstrated a superior corrosion resistance for aerospace and specialty applications. Considering the information above, special issues on magnesium alloys are exposed in this book: casting technology; surface modification of some special Mg alloys; protective carbon coatings on magnesium alloys; fatigue cracking behaviors of cast magnesium alloys and also, magnesium alloys biocompatibility as degradable implant materials.
