Magnesium Plate

Magnesium alloys are mixtures of magnesium with other metals (called an alloy), often aluminum, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium is the lightest structural metal. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys. Plastic deformation of the hexagonal lattice is more complicated than in cubic latticed metals like aluminium, copper and steel; therefore, magnesium alloys are typically used as cast alloys, but research of wrought alloys has been more extensive since 2003. Cast magnesium alloys are used for many components of modern automobiles, and magnesium block engines have been used in some high-performance vehicles; die-cast magnesium is also used for camera bodies and components in lenses.

Practically, all the commercial magnesium alloys manufactured in the United States contain aluminum (3 to 13 percent) and manganese (0.1 to 0.4 percent). Many also contain zinc (0.5 to 3 percent) and some are hardenable by heat treatment. All the alloys may be used for more than one product form, but alloys AZ63 and AZ92 are most used for sand castings, AZ91 for die castings, and AZ92 generally employed for permanent mold castings (while AZ63 and A10 are sometimes also used in the latter application as well). For forgings, AZ61 is most used, and here alloy M1 is employed where low strength is required and AZ80 for highest strength. For extrusions, a wide range of shapes, bars, and tubes are made from M1 alloy where low strength suffices or where welding to M1 castings is planned. Alloys AZ31, AZ61 and AZ80 are employed for extrusions in the order named, where increase in strength justifies their increased relative.

Microstructure and Mechanical Properties of AZ31 Magnesium Alloy Strip Produced by Twin Roll Casting Yusuke Nakaura, Akira Watanabe and Koichi Ohori Technical Development Center, Mitsubishi Aluminum Co., Ltd., Susono 410-1127, Japan Twin roll casting has been used to produce AZ31 magnesium alloy strip. The size of the cast strip is 5 mm thick and 250 mm wide. The microstructure of the as-cast AZ31 alloy strip consists of columnar zones from the surface to mid-thickness region and equiaxed zone in the midthickness region. The secondary dendrite arm spacing varies from 5.0 to 6.5 mm through the thickness and width of the strip and is much smaller than 34 mm of AZ31 alloy DC ingot used for the comparison. In temperature ranging from room temperature to 400C, tensile strength and elongation of the as-cast strip are higher and smaller than those of DC ingot, respectively. Elongation is evidently improved by homogenization treatment and becomes more than that of DC ingot. Such an improvement of elongation is though to be caused by homogenization of segregation of Al and Zn atoms in the dendrite cell boundaries.

Introduction In recent years, magnesium alloys, which are the lightest commercial structural alloys and have superior specific strength and stiffness, good heat dissipation, good shielding capability against electromagnetic interference and recycling ability, have become a point of much interest with the view of weight reduction that improves earth environment, fuel consumption and emissions. Therefore the use of magnesium alloys in the automotive industry and in portable electronic equipment has increased recently. Now, the most are cast products, such as highpressure die casting or thixocasting, which involve many problems, such as poor surface quality, low yield and difficulty in the thinning or application in large-sized members. On the other hand, when wrought products are used, it can be expected that the above-mentioned problems in casting products will be improved. However, the present price of magnesium alloy sheet is extremely high for the following reason. That is, in conventional rolling process of magnesium alloy strips, a slab with the thickness of the order of 120– 300 mm is first homogenized and then hot rolling and heat treatment are repeated many times to obtain a thickness of 5– 6 mm. As a result, the manufacturing cost becomes extremely high. If the cost could become cheaper, the demand for the sheet is expected to increase greatly. So recently twin roll casting of magnesium alloys that enables production of 5–6 mm thick magnesium alloy strips directly from molten metal and thereby reduces much of the processing and thus reduces the manufacturing cost has become of great interest.1) Still more, twin roll casting has the metallurgical advantages of the microstructure refinement due to the high freezing rates. And the works related to this subject have been reported.2,3) The present work is aimed at establishing a cost–effective process of manufacturing magnesium alloy strips with high formability by directly producing magnesium alloy strips from molten metal using twin-roll casting. In this paper, the microstructure and mechanical properties of AZ31 alloy

Introduction

Magnesium (Mg) is strong, stiff, and lightweight, making it the most widely used element in engineered structures after iron and aluminum. Its strength and stiffness can be further improved when alloyed with aluminum.

Nevertheless, bulk mechanical properties rely greatly on chemical composition and thermomechanical history, as these factors influence microstructure. This article discusses the application of nanoindentation to measure the properties of individual phases within a commercially available alloy, AZ 61.

AZ 61 Magnesium Alloy

AZ 61 contains aluminum (nominally 6%), zinc (nominally 1%), and other trace elements. Table 1 summarizes the chemical composition for AZ 61. The presence of zinc and other trace elements has little impact on the microstructure, and the phase diagram is used to deduce the composition of slowly cooled AZ 61.

At 6% aluminum, the Mg-Al phase diagram deduces the interaction of two phases: an α phase that is Mg-rich and a β phase comprising the intermetallic compound Al12Mg17.

Table 1. Chemical composition of magnesium AZ 61 alloy [2].

Aluminum5-7
Zinc0.8-1
Copper<0.03
Silicon<0.01
Iron<0.01
Nickel<0.005

When the alloy cools from the liquid state, the α phase starts solidifying at about 620°C and the solidification process completes at 540°C, at which point the material exists completely in the α phase. The precipitation of the β phase begins at around 300°C and the mass fraction of this secondary phase keeps on increasing as the temperature continues to decrease. At temperatures less than 100°C, the β phase represents about 7.5% of the alloy.

Instrumentation

The Keysight Express Test option is used in this analysis due to its ability to achieve unprecedented testing speeds by implementing conventional indentation testing in an innovative way. Express Test carries out one complete indentation cycle per second, which includes approach, contact detection, load, unload, and movement to the next indentation site.

Express Test can quantitatively ‘map’ the elastic modulus and the hardness of a surface in a reasonable time. This quality is especially advantageous for analyzing multiphase metals like AZ 61.
