High-cycle fatigue behaviour and mechanism analysis of a forged TiZr-based alloy

Abstract: Fatigue resistance, particularly the endurance limit, is an important design consideration in engineering applications for TiZr-based alloys. The investigated Ti-20Zr-6Al-4 V (wt-%) alloy exhibited a high fatigue endurance limit of 775 MPa. Results showed that severe local stress concentration due to extensive dislocation pile-up at α/β interfaces was responsible for the crack initiation. A transition from a tensile mode to a shear mode crack was observed during crack propagation. Many striations as well as so… Show more

“…However, except carrying out S-N curve tests again, there is no effective method to evaluate fatigue life for compressive mean stress states yet. It is true that it is better to derive fatigue life and limit evaluation methods from micro fatigue mechanisms [19][20][21][22][23] for different mean stress states. However, from the view of engineering application, developing a phenomenological evaluation method is also very meaningful.…”
