magnesium, when exposed to chloride ions in a non-oxidizing medium. For example, the as-extruded magnesium alloy AM60 was immersed in natural 3.5% NaCl solution, and the corrosion pits occurred on the surrounding of AlMn particles. Fig. 4: Scheme of
The AM60 MMC as well as AK7 MMC, each with the addition of 4 wt.% of cordierite, were subjected to an XRD analysis to explicitly identify the chemical composition of its phases (Fig. 4 and 5, respectively). The main phase in AM60 alloy was Mg 0.976Al 0.024 phase (indied in Fig. 1 and 2 as a
Magnesium alloys, which were created explicitly for additive manufacturing, do not exist so far. This is precisely the area in which the LKR team is currently conducting research. A new type of material system has already been presented that surpasses known materials in terms of processability and strength.

A new steel mold gravity casting magnesium alloy of low-cost, high strength, and high ductility has been developed and studied. This new magnesium alloy, which is designated as IMR-41, exhibits high strength (Yield Tensile Strength≈145 MPa, Ultimate Tensile Strength≈280 MPa) and high ductility (Elongation≈8%) at room temperature.
strip casting for magnesium alloys [4-6]. This paper describes the development of twin roll casting technology for magnesium alloys such as AZ31, AM60, AZ61 and AZ91. The cast magnesium alloy sheets were hot-rolled in an elavated temeparature
The magnesium alloy strip tends not to stick to the roll. Therefore, the lubricant was not used. Non-use of the lubricant useful to reduce the cost of magnesium sheet. Sheet of AM60 and AZ91 for commercial is not existed. The reason that hot roll of
of magnesium alloys for automotive appliions due to its low cost and high volume production of near net shape parts. AZ91 and AM60 are the most common die-cast alloys, as the former has excellent castability and strength and the latter outstanding
The present invention relates to a non-coustible magnesium alloy, comprising one of elements of Al at 0.1˜3 wt %, La at 0.1˜3 wt %, Nd at 0.1˜3 wt %, or Y at 0.005˜3 wt %; 0.5˜10 wt % of Ca; and the remainder of conventional

Magnesium alloy has many excellent properties, easy processing, low processing cost, good heat dissipation, thermal conductivity, and good electrical conductivity; shock absorption, anti-electromagnetic interference of excellent; density is small, plastic good, good superconductivity, and storage rich.
First published on 2nd March 2020 The effect of the addition of alcohol to a Na 3 PO 4-based electrolyte on plasma electrolytic oxidation (PEO) of AZ31B magnesium alloy was investigated.Anodization with spark discharge was conducted in Na 3 PO 4-based electrolyte containing various alcohols (e.g., ethanol, ethylene glycol, and glycerol) at a constant current density of 200 A m −2 and a
ABSTRACT The grain refining technique of AZ91D magnesium alloy by MgCO 3 has been investigated. The refining mechanism and tensile properties of the resulting alloy have also been discussed. The results indie that MgCO 3 can decrease its grain size from 311 to 53µm. m.
The only method currently available for completing such joints is bolting, but this adds weight and cost, requires accurate alignment and can create problems of fretting and wear between the bolt and the softer magnesium alloy.

23/12/2019· Alloy AZ91D is the most widely used magnesium die cast alloy and has an excellent coination of mechanical properties, corrosion resistance, and castability. Corrosion resistance is achieved by enforcing very strict limits on three metallic impurities—iron, copper and nickel.
5/9/2017· Using this insight we synthesized a surprisingly simple, compositionally lean, low-cost and industry-compatible new alloy which is over 4 times more ductile and 40% stronger than pure magnesium
In recent years, although a lot of positive results about the modified-AZ91, AM60 and WE43 casting magnesium alloys with various additions, Mg-Al/Zn/Sn based low cost casting magnesium alloys, Mg-Gd/Nd based high strength casting magnesium alloys and
It is better to prepare high performance mg RE alloy by using low cost electrolytic mg re master alloy than by using rich RE alloy in terms of burning loss rate, recovery rate and cost. The addition of Nd and y not only can not change the original grain size of AZ91 alloy, but also can produce solution strengthening effect.
