G115 steel is a prime candidate for key components in ultra-supercritical (USC) power
plants. In this study, G115 welded joint of 15 mm thickness had been successfully fabricated …

Abstract Effects of strain amplitude on the isothermal fatigue (IF) and thermomechanical
fatigue (TMF) behaviors of 316LN stainless steel were comparatively studied. The physical …

Thermomechanical fatigue (TMF) behaviour of 316L is investigated based on the internal
stress and microstructural characterization at various cyclic stages. Results reveal that the …

In this paper, the competition mechanism between protectiveness and harmfulness of
oxidation, as well as the effects of cycle period, mean stress and temperature on the damage …

In-phase and out-of-phase thermomechanical fatigue (TMF) tests in the temperature range
of 200–400° C and isothermal fatigue (IF) tests at 400° C were conducted to investigate …

New heat-resistant steel containing 9 wt% Cr has been used for Ultra-supercritical (USC)
power plants at temperatures up to 650° C. The microstructure, mechanical properties, and …

Isothermal (IF) and thermo-mechanical fatigue (TMF) tests were conducted on 316L welded
joints to investigate the effects of phase angle (in-phase (IP), clockwise-diamond (CD), and …

In the present work, a numerical simulation based on the crystal plasticity finite element
(CPFE) method is conducted to capture the different mechanical responses and damage in …

Temperature variation plays a crucial role in the safe operation of welded structures during
long-term high-temperature service. The present work aimed to explore the relationship …

The role of thermal cycling on the deformation behaviour and microscopic damage
mechanisms of 316L stainless steel are clarified through isothermal fatigue (IF) and …
