摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a titanium alloy increased in the content of group Va elements by which composition fluctuations and solidification segregation can be more reduced than ever before.
SOLUTION: The manufacturing method comprises: a melting step in which vacuum arc melting is performed using, as a consumable electrode 1, of a powder compact prepared by compacting a uniform raw material powder of 20μm to 1 mm average particle size which is regulated into a desired overall composition consisting of a group of alloying elements including at least group Va elements and titanium as the main balance; a solidification step in which the resultant molten alloy 2 melted in the melting step is successively cooled to undergo solidification; and a heat treatment step in which the resultant alloy ingot 3 prepared by solidification in the solidification step is subjected to homogenizing heat treatment. By this method, the titanium alloy characterized as follows can be obtained: the above group of alloying elements is contained, when the total is 100 mass%, in an amount of 15 to 60 mass% in sum; and the "amount of element segregation" of the elements included in the group of alloying elements and Ti is made to ≤0.9 mass%. The above "amount of element segregation" means the microscopic amount of segregation with respect to each element, occurring in a minute area of the titanium alloy.

摘要： PROBLEM TO BE SOLVED: To provide a method for melting a titanium alloy containing many Va group elements.
SOLUTION: The method for manufacturing the titanium alloy comprises: a melting step wherein a uniform raw-material powder of 1μm to 5 mm average particle size, which is regulated into a desired total composition consisting of a group of alloying-elements containing at least Va group elements and the main balance Ti, is compacted into a desired shape and the resultant powder compact is heated to undergo melting; and a solidification step wherein the resultant molten alloy melted in the above melting step is successively cooled to undergo solidification. After the solidification step, the titanium alloy containing the above Va group elements in the amount of 15 to 60 mass% in total (when the whole is 100 mass%) and having an alloy composition practically uniform regardless of the part of the alloy can be obtained. By melting the powder compact composed of the powder with the specific particle size, the uniform titanium alloy which hardly causes unmelting even in the case where large amounts of high-melting-point alloying elements are contained and is minimal in composition fluctuations, solidification segregation, etc., can be obtained.
