Add to ORKGThree lots of tantalum/316 stainless steel bimetallic tubing were thoroughly non-destructively evaluated. Two of the lots were fabricated by co-extrusion to size and the third by explosive bonding to size. Although dimensional control of all three lots of tubing was excellent, the lot co-extruded over a mandrel was superior to the other two lots in all respects.Performing organization report no.: WANL-PR-PPP-001."NASA CR-1575.""May 1970."Cover title.Includes bibliographical references (p. 68).Three lots of tantalum/316 stainless steel bimetallic tubing were thoroughly non-destructively evaluated.
