Patent ID: 8088231

Claim:
A metallic article made of constituent elements in constituent-element proportions, wherein the article was produced by a method comprising the steps of: furnishing at least one nonmetallic precursor compound, wherein all of the nonmetallic precursor compounds collectively contain the constituent elements in their respective constituent-element proportions, and wherein the constituent elements comprise titanium, at least one alloying element capable of alloying with titanium and present in proportions to form a titanium-base alloy, and an additive element selected from the group consisting of magnesium, calcium, scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium, and mixtures thereof, and wherein at least one additive element is present at a level greater than its room-temperature solid solubility limit in the titanium-base alloy; chemically reducing the precursor compounds to produce a titanium-base alloy material; and consolidating the alloy material to produce a consolidated metallic article; wherein each step in producing the metallic article is performed without melting for any more than about 10 seconds, and wherein the produced article has a matrix in which a first set of stable oxide dispersoids and a second set of stable oxide dispersoids are both dispersed therein, wherein the first set of stable oxide dispersoids are coarse relative to the second set of stable oxide dispersoids and the article further includes the additive element present in an unreacted discrete phase and in solid solution.
