Fiber reinforced titanium matrix composites (TMCs) are attractive materials for future aerospace applications. Reinforcement of Ti alloys with SiC fibers leads to a significant increase on strength and stiffness, especially under high stress loading or at elevated temperatures. Mechanical properties of TMCs are strongly influenced by thermal residual stresses (TRS). A reduction of TRS leads to an increase in fully reversed high cycle fatigue resistance of TMCs at room temperature. Reduction of TRS can be easily obtained by pre‐straining during single tension loading of TMCs in the as processed condition.
