IIT, North Texas varsity develop magnesium alloy which can replace steel, aluminium in automobiles The researchers say the current industrial appliion of wrought magnesium alloys in structural
Interestingly, only magnesium-yttrium alloy with metallic surface degraded slower in PBS than in DI water, while all the other samples degraded faster in PBS than in DI water. Clearly, the results showed that the alloy composition, presence or absence of surface oxide layer, and presence or absence of physiological salt ions in the immersion solution all influenced the degradation rate and mode.
The effects of yttrium on the microstructure and mechanical properties of AZ91 magnesium alloy were studied in this paper. The experimental results show that magnesium alloy
Among these alloys, ZRE1 magnesium alloy exhibits good creep properties up to 200 C. This alloy containing zinc, rare earth metals and zirconium. Zinc is usually used in coination with aluminum, zirconium, rare earths, or thorium to produce precipitation-hardenable magnesium …
Magnesium is the lightest of all light metal alloys and therefore is an excellent choice for engineering appliions when weight is a critical design element. It is strong, has good heat dissipation, good damping and is readily available. Its properties make it easy to
2013/3/13· “We selected an alloy of magnesium, gadolinium, yttrium, silver and zirconium because we thought we could introduce the faults to that specific alloy using hot rolling,” says Dr. Yuntian Zhu, a professor of materials science and engineering at NC State and co
The aim of this in vivo study was to examine the degradation and biocompatibility of the WE43 magnesium alloy containing magnesium yttrium, rare earth elements, and zirconium over a one-year long-term follow-up period. Additionally, we compared anodized WE43
2013/5/2· The present study investigated the potential for the use of degradable magnesium-3% yttrium alloy (W3) to serve as an extraluminal tracheal stent in a canine model. The host response to the scaffold included the formation of a thin, vascularized capsule consisting of collagenous tissue and primarily mononuclear cells.

Magnesium is a silvery-white metal that can be obtained by electrolysis of magnesium salts from brine. Magnesium WE54-T6 is a high strength fully heat treatable magnesium-based casting alloy that can be used at temperatures up to 300 C.
2018/1/29· Magnesium alloys are widely used in aerospace and automotive industry due to their low density, good mechanical properties, and good castability. Their main disadvantage is low maximum working temperature (about 120°C for Mg-Al alloys). This led to the development of Mg-Al-RE or Mg-RE-Zr alloys, which can work up to 250°C. The chapter will relate to the sand cast and high pressure die …
2019/2/15· High-temperature oxidation of magnesium alloys in air typically involves an initial oxidation stage with parabolic kinetics and a subsequent oxidation stage with accelerated kinetics which are linear or power-law kinetics.13,30 The parabolic growth stage is considered as an oxidation incubation period, during which a compact protective oxide layer forms and isolates the magnesium substrate
The magnesium-yttrium alloy was more susceptible to degradation in water than the high purity magnesium alloy. However, the polished surface magnesium-yttrium alloy had the least susceptibility to degradation in phosphate buffered saline (PBS) among all the sample compositions and surfaces.
