Abstract
An austenitic stainless steel adaptor used in the command pressure dis tributor assembly of a test stand for liquid fuel engines cracked duri ng one of the ground tests. The failed component was studied through m etallographic techniques to analyse the cause of failure. The study re vealed that the crack initiated at a location containing a brittle iro n precipitate rich in silicon and propagated by vibration-induced fati gue through the tube wall.
