Taira, S.:Relationship between thermal fatigue and K44X is a cost effective solution for high temperature low-cycle fatigue at elevated temperature, Fatigue at applications because of its really good thermal fatigue elevated Temperatures, ASTMSTP 520, ASTM, behavior due to its lower thermal expansion coefficient (1973) and its oxidation Damage Mechanisms of Stainless Steels under Thermal FatigueApr 01, 2014 · This test is well suited to perform a study of damage mechanisms and to compare stainless steel grades. Examination of the failed specimens indicated that cracks could be mainly attributed to out-of-phase (OP) thermal fatigue process especially in case of ferritic grades.

Apr 16, 2020 · Fatigue crack growth tests using ferritic steel specimens were performed in air environment at room and high temperatures. From the crack closures obtained by the tests, it was found a new boundary which is smaller than the definition given by the Appendix A-4300. Fatigue limit prediction of ferritic-pearlitic ductile The mechanical behavior of ductile cast iron is governed by graphite particles and casting defects in the microstructures, which can significantly decrease the fatigue strength. In our previous study, the fatigue limit of ferritic-pearlitic ductile cast iron specimens with small defects could successfully be predicted based on the parameter
Nov 25, 2019 · Obviously, it is crucial to understand the interaction mechanism among fatigue damage, creep damage and oxidation damage. In the present study, 15CrNbTi and 15Cr0.5MoNbTi ferritic stainless steels are chosen to investigate the fatiguecreep behavior in the simulated exhaust atmosphere and in argon at 800 °C. Influence of Gaseous Hydrogen on Fatigue Behavior of This work studies the fatigue behavior of ferritic stainless steel 1.4005IA optimized for electromagnetic properties under varying environmental conditions. Fatigue-life of air-tested specimens are compared to specimens which are electrochemically hydrogen precharged and loaded in a pressurized gaseous hydrogen atmosphere.
Jun 01, 2014 · Creep tests were carried out at 823 K (550 °C) and 210 MPa on Reduced Activation Ferritic-Martensitic (RAFM) steel which was subjected to different extents of prior fatigue exposure at 823 K at a strain amplitude of ±0.6 pct to assess the effect of prior fatigue exposure on creep behavior. Extensive cyclic softening that characterized the fatigue damage was found to be immensely Intergranular Fatigue Crack Initiation and Its Associated The fatigue crack initiation and propagation behavior of a water-quenched binary FeC fully ferritic steel was investigated though rotating-bending fatigue testing. Intergranular and transgranular crack initiation and propagation were observed.
Abstract:In recent, ferritic stainless steels are widely used in high temperature structure because of their high resistance in thermal fatigue and low prices. Tensile and low cycle fatigue (LCF) tests on 429EM stainless steel were performed at several temperatures from room temperature to 600°C. Elastic modulus, yield stress and ultimate tensile strength (UTS) decreased with increasing temperature.

Feb 01, 1999 · The material and loading parameters that influence fatigue life in LWR environments are defined. Statistical models have been developed to estimate the fatigue lives of these steels in LWR environments, and design fatigue curves have been developed for carbon and low-alloy steel components in LWR environments. The Role of Microstructure in Fatigue Crack Initiation and Keywords:Ferritic-martensitic steel, LCF, microstructure, microcrack nucleation 1. Introduction Previous low-cycle fatigue studies on 9-12Cr ferritic-martensitic steels showed that cyclic softening occurs due to microstructural instability over a wide range of temperatures [1-5]. This effect could become a
The work reported here results from a study on the effect of martensite content on the high cycle fatigue performance in which possible correlations between the quasi-static and fatigue properties have been sought. Commercial grade SAE 5115 carburizing steel was used in this study The influence of Cr and Ni on the high-temperature low Thus, in the present study, the effects on mechanical properties of adding Cr and Ni to SiMo51 has been investigated with focus on low-cycle fatigue behavior in air, at temperatures up to 700°C. Both additions improve fatigue life but reduce elongation.
