SUBSTANCE: invention relates to nonferrous metallurgy, particularly, to flux metals for melting and refinement of deformable yttrium containing magnesium alloys. Flux metal possess a high refining capability removing metal impurities, prevents from yttrium loss and has the following content, wt %: MgCl 2 17.0-32.0, CaF 2 1.0-4.0, NaBr 3.0-7.0
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.
Yttrium metal mainly apply to production of red phosphor ( YVO 4:Eu, Y 2 O 3:Eu, Y 2 O 2 S:Eu) of colour TV picture tube. It is also for some ray filter, superconductor, super alloy and special glass. Yttrium ingot can apply as nodulizing agent in nodular cast iron, desoxidant for vanadium and other nonferrous metals. It can improve property and strength of some alloys and metals as chromium

Jun 14, 2013· In the immersion solution of phosphate buffered saline (PBS), the magnesium-yttrium alloy with metallic surface degraded the slowest, followed by pure magnesium with metallic or oxide surfaces, and the magnesium-yttrium alloy with oxide surface degraded the fastest. However, in deionized (DI) water, the degradation rate showed a different trend.
