Fatigue Behavior and Fatigue Damage of a Ti-6242/SCS-6 Metal Matrix Composite

摘要

High temperature titanium alloy matrices reinforced with continuous SiC fibers show very high tensile strength and fatigue resistance which are retained at high temperatures. Results of isothermal and thermo-mechanical fatigue tests on Ti-6242/SCS-6 are presented. The mechanical data were determined to identify the material parameters of a viscoplastic material model, which will be used to simulate the behavior of the composite.
