A magnesium alloy containing Al, Sr, Ca, and Mn, with the balance being Mg and inevitable impurities, the magnesium alloy having: a structure having an &#x3b1;-Mg phase, and a precipitate dispersed in at least one of a grain boundary of the &#x3b1;-Mg phase and a cell boundary, the precipitate including: at least one phase selected from a group A consisting of an AlSr phase, an AlSr phase, a (Mg, Al)Sr phase, and a (Mg, Al)Sr phase; and at least one phase selected from a group B consisting of an AlCa phase and a (Mg, Al)Ca phase, the magnesium alloy having, in a cross section, a total area rate of a group A precipitate and a group B precipitate of greater than or equal to 2.5% and less than or equal to 30%.

Magnesium alloy and magnesium alloy member

A magnesium alloy is provided that includes: 5.0 mass % or more and 15.0 mass % or less of Al; 2.5 mass % or more and 7.0 mass % or less of Sr; 0.05 mass % or more and less than 3.0 mass % of Ca; and 0.1 mass % or more and 0.6 mass % or less of Mn, with a remainder including Mg and inevitable impurities.

Magnesium alloy

The present invention includes photocurable, liquid polymers incorporating coumarin ester endgroups into their molecular structure, which polymers are crosslinked upon irradiation with ultraviolet light by photochemically allowed [2+2] cycloaddition reactions among the chain ends, and which crosslinked polymers are useful in the preparation of medical devices, tissue engineering scaffolds, drug delivery systems and, in particular, in vivo preparation of implants in an open surgical procedure or laproscopically.
