Claim:
A magnesium alloy, consisting of: Y: 0.5-10 weight-percent, Zn: 0.5-6 weight-percent, Ca: 0.05-1 weight-percent, Mn: 0-0.5 weight-percent, Ag: 0-1 weight-percent, Ce: 0-1 weight-percent, Zr: 0-1 weight-percent or Si: 0-0.4 weight-percent, wherein the amounts are based on weight-percent of the alloy and Mg and manufacturing-related impurities constitute the remainder of the alloy to a total of 100 weight-percent, wherein the magnesium alloy has a monophasic structure, wherein the magnesium alloy has an effective amount of one or more intermetallic phases having a volume amount of less than about 3 vol. % to produce an alloy having a grain size of less than about 20 μm, and wherein the grain size of the intermetallic phases is less than about 3 μm.
