Title:
HIGH-STRENGTH LOW-ALLOYED TITANIUM ALLOY AND ITS PRODUCTION METHOD
Document Type and Number:
Japanese Patent JP2004269982
Kind Code:
A
Abstract:
To provide a high-strength low-alloyed titanium alloy having a tensile strength of ≥750 MPa, and a production method which can produce such a titanium alloy using an inexpensive, low-quality sponge titanium as a raw material.
The high-strength low-alloyed titanium alloy has an alloy composition comprising 0.2-0.8% O, 0.01-0.15% C, 0.01-0.07% N, 0.3-1.0% Fe and the balance substantially being Ti. When producing this, the low-quality Ti sponge containing ≥0.01% N and ≥0.2% Fe is used as a part of the raw material as sources of N and Fe components.
