This paper focus on factors attributing to casing failure, their failure mechanism and the
resulting failure mode. The casing is a critical component in a well and the main mechanical …

The coupling effects of microstructure and macro-scale defects are significant for the fatigue
properties of metallic materials. However, this correlation is still vague for additively …

The cyclic deformation and damage behaviors of the Fe–Mn and Fe–Mn–C TRIP/TWIP
steels are comprehensively studied in a wide range of strain amplitude (from 0.3% to 8.0%) …

A series of strain-controlled creep-fatigue tests with various dwell times and strain ratios are
carried out on a nickel-based superalloy at 650° C. Aiming at the mechanical understanding …

To study the effect of the aging state on the low-cycle fatigue (LCF) performance of 7075 Al
alloy, LCF experiments with different strain amplitudes (Δε/2= 0.5%-Δε/2= 0.9%) were …

High-entropy alloys (HEAs) represent a new class of materials with excellent mechanical
properties. However, more studies on the fatigue behavior of HEAs are urgently required …

Compared to stress controlled high-cycle fatigue, enhancing strain controlled low-cycle
fatigue (LCF) properties of material is much more difficult and less reported. In this study, we …

Nickel-based single-crystal superalloys are widely used in the manufacture of aeroengine
turbine vanes for their excellent high-temperature performance. Low-angle grain boundaries …

Cyclic deformation behavior and damage mechanisms of Cu-Mn alloys with high stacking
fault energies (SFE) were systemically investigated at constant total strain amplitude in the …

A large number of strain-controlled creep-fatigue tests under wide loading waveforms are
conducted at 650℃ in nickel-based forged GH4169 superalloy. Comprehensive …
