Title:

HEAT TREATMENT METHOD FOR α+β TITANIUM ALLOY, AND α+β TYPE TITANIUM ALLOY PRODUCT

Document Type and Number:

Japanese Patent JP2017048410

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a heat treatment method for an α+β type titanium alloy capable of satisfying the characteristics required as those of a biomaterial while realizing precise dimensional shape, and an α+β titanium alloy product produced using the same.SOLUTION: Provided is a heat treatment method for a lamination-molded α+β type titanium alloy, comprising: a rapid heating step where heating is performed for 0.1 to 30 s at 800 to 1,200°C; and a rapid cooling step where, after the rapid heating step, cooling is performed at a cooling velocity of 40°C/s or higher.SELECTED DRAWING: Figure 3
