Conclusions 1. The effect of the structure of alloys VT3-1 and VT-18 on their cyclic strength depends on the conditions of loading. 2. Under loading with a pulsating cycle (extension, R=0) at room temperature, rods of alloys VT3-1 and VT-18 with a fine-grained equiaxial structure are superior in cyclic streghth to metal with a lamellar structure. 3. At 450°C under asymmetrical tension with a mean stress σn=30 kgf/mm2, the fine-grained equiaxial and the lamellar structures behave in the same way; in the case of alloy VT-18 the lamellar structure gives a higher resistance to fatigue failure at 600°C and σn=25.0 kgf/mm2.
