Two fundamental questions have been addressed on a recently developed high strength β Ti alloy, Ti-5Al-5V-5Mo-3Cr, with respect to two very different types of microstructures, one bimodal and the other fully lamellar, both having similar yield strength. Those are: 1) If and what would be the difference in their LCF response? 2) What would be the sequence of plastic deformation among the phases of different morphology, β, globular α and lath α? TEM based deformation micro mechanism explained the LCF response at various strain amplitudes. Crack path-microstructure interaction explained the difference in life, specifically observed at low strain amplitude
