Hold-time Effects on Low-cycle-fatigue Behavior of Hastelloy® X Superalloy at High Temperatures
Total strain-controlled low-cycle-fatigue tests with and without hold times were performed at temperatures ranging from 816°C to 982°C in a laboratory air on a nickel-based superalloy, HASTELLOY X. The influence of hold times on the cyclicstress response and fatigue life was studied. At the temperatures considered, the alloy exhibited initial cyclic hardening, followed by a saturated cyclic-str...
متن کاملEffect of Low Cycle Fatigue Predamage on Very High Cycle Fatigue Behavior of TC21 Titanium Alloy
The effect of low cycle fatigue (LCF) predamage on the subsequent very high cycle fatigue (VHCF) behavior is investigated in TC21 titanium alloy. LCF predamage is applied under 1.8% strain amplitude up to various fractions of the expected life and subsequent VHCF properties are determined using ultrasonic fatigue tests. Results show that 5% of predamage insignificantly affects the VHCF limit du...

متن کاملA Novel Viscosity-Based Model for Low Cycle Fatigue Creep Life Prediction of High-Temperature Structures
Damage evolution during low cycle fatigue, creep, and their interaction behavior is actually a ductility exhaustion process in response to cyclic and static creep. In this article, a novel viscosity-based model for low cycle fatigue creep life prediction is presented in an attempt to condition viscosity-based approaches for general use in isothermal and thermo-mechanical loading. In this model,...
متن کاملPlastic strain localization and fatigue micro-crack formation in Hastelloy X
In polycrystalline metals, local deformation heterogeneities induced by the microstructure influence fatigue crack initiation and micro-crack propagation. The localization in plastic strains associated with heterogeneous deformation has been described as a necessary condition and a precursor for the nucleation of fatigue cracks. However, a clear and quantitative assessment of the correlation be...
