This article deals with nanoindentation analysis of welded overlay layer of Inconel 625 alloy on 16Mo3 steel and their interface (transition zone). The microstructure of weld metal is analyzed, as well as the weld-on steel and subsequently nanoindentation properties (nanohardnes, reduced modulus of elasticity) of selected structural components. The weld of Inconel 625 alloy is realized on a tube made of 16Mo3 steel, which is bent by the so-called critical bending (d≤0,7D). The article also deals with the change of investigated properties of the weld after that bending. The samples prepared from the areas with highest compressive and tensile load after the tube bending on outer, respectively inner bend arc were used for the research. Nanoindentation analysis was performed with using a Hysitron Triboindenter TI950 and its evaluation software Triboscan. nanoindentation weld overlay Inconel 625 alloy 16Mo3 steel microstructure

“…A few studies on bending fatigue testing in the LCF regime have been conducted to evaluate the size effect and the influence of strain gradient on fatigue failure life. Kulesa et al [9], Kurek et al [10], and Kurek [11] developed a lab-made bending testing apparatus to conduct strain-controlled cyclic bending and evaluated the relationship between fatigue failure life and total strain amplitude. They demonstrated that the fatigue life of bending specimens was slightly longer than that of T/C specimens.…”

Influence of Strain Gradient on Fatigue Life of Carbon Steel for Pressure Vessels in Low-Cycle and High-Cycle Fatigue Regimes

et al. 2022

This paper discusses how the strain gradient influences the fatigue life of carbon steel in the low-cycle and high-cycle fatigue regimes. To obtain fatigue data under different strain distributions, cyclic alternating bending tests using specimens with different thicknesses and cyclic tension–compression tests were conducted on carbon steel for pressure vessels (SPV235). The crack initiation life and total failure life were evaluated via the strain-based approach. The experimental results showed that the crack initiation life became short with decreasing strain gradient from 102 to 106 cycles in fatigue life. On the other hand, the influence of the strain gradient on the total failure life was different from that on the crack initiation life: although the total failure life of the specimen subjected to cyclic tension–compression was also the shortest, the strain gradient did not affect the total failure life of the specimen subjected to cyclic bending from 102 to 106 cycles in fatigue life. This was because the crack propagation life became longer in a thicker specimen. Hence, these experimental results implied that the fatigue crack initiation life could be characterized by not only strain but also the strain gradient in the low-cycle and high-cycle fatigue regimes.

“…In most cases, the tests were performed phase-aligned with controlled values of bending and torsional moments amplitudes (dynamic load) [23][24][25][26][27]. Testing of materials subjected to bending and torsional loads, with controlled kinematic load, is much less common; however, some studies [28,29] analyzed essentially aligned kinematic loads causing bending and torsion. Literature sources on material testing in both possible load control variants (dynamic and kinematic) is lacking.…”

In this study, a novel test system for estimating bending and torsion fatigue under selectable kinematic and dynamic loading modes was constructed. Using S355J2 steel specimens, a series of tests were conducted to determine material sensitivity to different load paths and loading modes. The experimental results were supplemented with the results of numerical analyses, on the basis of which the components of strain and stress tensors for subsequent analyses were determined in the entire working part of the specimen. An original method for determining specific strain energy components was used. The experimental results showed the grouping of data according to the mode of loading chosen. This could signify that the selected fatigue models are sensitive to certain loading scenarios. We performed in-depth data analysis and complex numerical simulations, formulating likely explanations for the observed effect.
