Claim:
1. A downhole tool comprising: at least one component of the downhole tool made of a doped magnesium alloy solid solution formed from a single melt that at least partially degrades in the presence of an electrolyte, wherein the doped magnesium alloy is selected from the group consisting of: a doped WE magnesium alloy comprising 86.6% to 90.6% magnesium, about 4% rare earth metal yttrium, about 4% rare earth metal that is not yttrium, 1% to about 5% dopant from the group consisting of iron, nickel, copper, and any combination thereof, and selected about 0.4% supplemental material of zirconium, each by weight of the doped WE magnesium alloy; a doped AZ magnesium alloy comprising about 88.5% magnesium, about 9% aluminum, about 0.7% zinc, 1% to about 5% dopant selected from the group consisting of iron, nickel, copper, and any combination thereof, about 0.2% supplemental material of manganese, and about 0.3% supplemental material of zinc, each by weight of the doped AZ magnesium alloy; a doped AZ magnesium alloy comprises about 94.5% magnesium, about 3% aluminum, about 1% zinc, 1% to about 5% dopant selected from the group consisting of iron, nickel, copper and any combination thereof, and about 0.3% supplemental material of manganese, each by weight of the doped AZ magnesium alloy; a doped ZK magnesium alloy comprising about 91.7% magnesium, about 5.9% zinc, about 0.2% zirconium, and about 2% dopant selected from the group consisting of copper, nickel, iron, and any combination thereof, each by weight of the doped ZK magnesium alloy; a doped ZK magnesium alloy comprising about 89.9% magnesium, about 3.2% zinc, about 0.6% zirconium, and about 6.3% dopant selected from the group consisting of copper, nickel, iron, and any combination thereof, each by weight of the doped ZK magnesium alloy; and a doped AM magnesium alloy comprising about 91.4% magnesium, about 6% aluminum, about 0.2% manganese, about 2% dopant selected from the group consisting of copper, nickel, iron, and any combination thereof, about 0.2% supplemental material of silicon, and about 0.2% supplemental material of zinc, each by weight of the doped AM magnesium alloy.
