摘要:
A method for preparing a filler-metal weld rod of a filler-metal composition includes the steps of centerless grinding the filler metal weld rod of a forced mixture of a mass of titanium aluminide intermetallic alloy powder that was used to form the weld rod, and hot isostatic pressing the filler-metal weld rod at a temperature greater than 2150° F., at a pressure between about 15,000 pounds per square inch and about 25,000 pounds per square inch and for a time of about 1 to 5 hours, thereby increasing the relative density to between about 98% and about 99%.
