METHOD OF ULTRASONIC INSPECTION OF AS-CAST TITANIUM ALLOY ARTICLES

摘要

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.

1. A method comprising the steps of:
providing an as-cast titanium article made up of a titanium base alloy and boron in a range of about 0.05 to 0.20 percent by weight; and ultrasonically inspecting the as-cast titanium article to determine whether the article has internal flaws.
