Document Type and Number:
WIPO Patent Application WO/2019/044851
Kind Code:
A1
Abstract:
Provided is a clock component including a titanium alloy, wherein the titanium alloy contains, in percent by mass, 1.0-3.5% of Al, 0.1-0.4% of Fe, 0.00-0.15% of O, 0.00-0.10% of C, 0.00-0.20% of Sn, and 0.00-0.15% of Si, the balance being Ti and unavoidable impurities. The average grain size of α-phase crystal grains is 15.0 μm or less, the average aspect ratio of the α-phase crystal grains is 1.0-3.0 (inclusive), and the variation coefficient of the number density of β-phase crystal grains dispersed in the α phase is 0.30 or less.
