Description
Summary:An austenitic stainless steel adaptor used in the command pressure distributor assembly of a test stand for liquid fuel engines cracked during one of the ground tests. The failed component was studied through metallographic techniques to analyse the cause of failure. The study revealed that the crack initiated at a location containing a brittle iron precipitate rich in silicon and propagated by vibration-induced fatigue through the tube wall.
