Abstract
The present invention relates to a process for friction welding molybdenum-rhenium alloys which include from about 10% to about 50% by weight. The process of the invention comprises effecting a relative rotation of two MoRe work pieces at rim surface speeds up to about 4,000 to 8,000 inches per minute, forcing the work pieces into frictional contact under an axially applied pressure of about 3,000 to 20,000 pounds per square inch of interface surface.
