Multi-component magnesium-based alloy consisting essentially of about 1.0-15.0 wt. % of scandium, about 0.1-3.0 wt. % of yttrium, about 1.0-3.0 wt. % of rare-earth metal, about 0.1-0.5 wt. % of zirconium. Purity degree of magnesium base is not less of 99.995 wt. %. Impurities of Fe, Ni and Cu do not exceed 0.001 wt. % of everyone, the contents of other impurity in an alloy does not exceed 0.005 wt. %. The alloy demonstrates an improved combination of strength, deformability and corrosion resistance at room temperature. The alloy does not contain harmful and toxic impurities. The alloy can be used in the various practical applications demanding a combination of high strength, deformability and corrosion resistance, preferably in the field of medicine.

Magnesium-based alloy with improved combination of mechanical and corrosion characteristics

The present invention relates to compositions and structure of deformable alloys on the basis of magnesium with an optimum combination of mechanical properties (strength, plasticity) and a resistance to corrosion, including in vivo. Alloys of the new group possess an excellent formability at room temperature, high corrosion stability in sodium chloride solution, excellent heat resistance and can be used in various technical applications, particularly in vivo as a structural material for stents.

Magnesium-based alloy

The method comprises the steps of forming an elongated tubular metal casing This elongated tubular metal casing is then coiled. The coiled tubular casing is filled with a material capable to irradiate radioactive radiation. The material is in liquid state with following crystallization in the coiled tubular casing The filled coiled tubular casing is then sealed at its ends

Method for producing a coiled body for irradiating radioactive radiation

A filament for irradiating a living body has a core material capable of irradiating radioactive radiation clad in a tubular casing of protective material different from the material forming the core. The materials forming the core and casing have a purity not less than 99.5 atomic percent and a grain size not exceeding 30 .mu.m and the outer diameter of the filament is not less than 80 .mu.m.
