Title:
TITANIUM ALLOY AND METHOD OF FORMING A TITANIUM ALLOY
Document Type and Number:
WIPO Patent Application WO/2018/136641
Kind Code:
A3
Abstract:
An alloy and method for producing an alloy is presented. The Titanium alloy has Ti-xCr-yFe-zAl, where 16>x>10, 4>y>0, and 6>z>0, where the alloy is heated to a temperature between 250 and 500 degrees C. Optionally, the alloy can be subjected to strain while at the elevated temperature. A portion of the Titanium alloy is converted from a first beta phase to a second athermal omega phase.
