It has been so long that I don't remember if the turbine engines I worked on had titanium blades or not, it sure doesn't ring any memory bells, Regardless the vanes in a turbine engine are subject to a number of different type of stress factors, violent, sudden impact stress was not one of them. The information I posted about the clyinder liners in Ti cylinders is from Smith and Wessons by the way.
