METHOD FOR ULTRASONIC TESTING OF ARTICLES FROM TITANIUM ALLOY IN CAST CONDITION

摘要

A method is presented for the non-destructive testing of cast titanium alloy objects using ultrasonic waves to detect internal defects, including a change in the grain structure in the solidified block structure by adding traces of boron to various titanium alloys. The ability to ultrasonically cast cast ingots or dolls, combined with improved hot workability due to the addition of traces of boron, enables an economical process for producing titanium alloy articles intended for high performance applications.
