  • Titanium welding wire, ultrasonically inspectable welds and parts formed therefrom, and associated methods
    Patent number: 9981349
    Abstract: A welding wire formed of a trace boron titanium base alloy is provided, along with welds formed from the wire and articles comprising one or more of such welds. A method may include forming such a weld or welds from such a welding wire, and may also include non-destructively inspecting titanium alloy articles comprising one or more of such welds using ultrasonic waves to detect internal flaws.
    Type: Grant
    Filed: November 5, 2014
    Date of Patent: May 29, 2018
    Assignee: Arconic Inc.

  • Method of ultrasonic inspection of as-cast titanium alloy articles
    Patent number: 9651524
    Abstract: A method is provided of non-destructively inspecting titanium alloy articles in the as-cast condition using ultrasonic waves to detect internal flaws, comprising modification of grain structure in the as-solidified ingot structure by the addition of trace boron to various titanium alloys. The ability to ultrasonically inspect as-cast billets combined with improved hot workability provided by trace boron enhancement permits an economical method of manufacture of titanium alloy articles destined for high performance applications.
