Abstract
Hybrid-reinforced titanium matrix composites (TMCs) were in-situ synthesized by common casting and hot-working technologies. High-temperature creep behavior of the matrix titanium alloy and composites was tested at 873, 923, and 973 K in the stress range from 20 to 300 MPa. Depending on the stress levels, creep behavior of the matrix alloy and composites was divided into two stress regions. Creep resistance of the composites was significantly enhanced by the reinforcements. Threshold stresses and stress transfer effects were introduced to explain the enhancement of creep resistance. In most cases, high volume fractions of reinforcements caused a deleterious effect on the creep resistance of composites. On the other hand, types and morphologies of reinforcements were the dominant factor contributing to the enhancement of creep resistance.
