“…For engineering computations the most suitable seem to be FEM based numerical methods making possible to calculate selected parameters of the process with the expected accuracy. However the modelling of the induction surface hardening is still a challenge and requires many new research activities [16][17][18][19][20].…”

The paper presents analysis of surface induction hardening of a cylindrical element made of steel 38Mn6. The mathematical model of the non-stationary process is elaborated. Calculations of coupled electromagnetic and temperature fields are provided by means of the Flux 2D software. Computations are compared with the measurements realized at the laboratory stand located in the Silesian University of Technology. The expected hardness distribution within the surface layer is noticed.Keywords: induction hardening, temperature field, simulation, electromagnetic field W artykule przedstawiono analizę indukcyjnego hartowania powierzchniowego elementu cylindrycznego wykonanego ze stali 38Mn6.

“…Roland et al [7] and Yang et al [8] showed that a stainless steel with surface mechanical attrition treatment and a pure Cu with surface mechanical grinding treatment had higher fatigue strength than the original materials, especially in high cycle fatigue regime. Other articles [10][11][12][13][14][15] also reported similar results of different materials with various types of surface treatments. All these investigations attributed the enhancement of the fatigue strength for the treated specimens or components to the grain refinement and the compressive residual stress caused by surface strengthening treatment.…”

A B S T R A C TThis paper experimentally investigated the behavior of fatigue crack growth of an axle steel with a surface strengthened gradient microstructure layer. First, the microstructure, residual stress and mechanical properties were examined as a function of depth from surface. Then the fatigue crack growth rate was measured via three point bending fatigue testing. The results indicated that fatigue crack growth rate decelerated first and then accelerated with the increase of crack length within the gradient layer. Especially, the fatigue crack was arrested in the gradient layer under relatively low stress amplitude due to the increase of threshold value for crack growth within the range of 3 mm from surface. Based on these results, the parameters of Paris equation and the threshold value of stress intensity factor range within the gradient layer were determined and a curved surface was constructed to correlate crack growth rate with stress intensity factor range and the depth from surface. The effects of microstructure, residual stress and surface notch on the crack growth behavior were also discussed.

“…6 and 7, for both normal stresses, r zz and r hh , the residual stress field is compressive over the two first millimetres, and then becomes tensile. The maximum compressive stress is quite small in surface area compared to the possible compressive stress that this kind of SIH treatment can generate in a similar kind of steel [1]. This might result from natural tempering occurring during quenching below MS (martensite starting).…”

“…Surface induction heating followed by quenching is one such treatment. One of the main features of surface induction hardening (SIH) is its large fatigue strength improvement [1]. This is also a cleaner process because it uses less toxic products than used in carburizing or nitriding.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. This paper proposes a method to assess the high-cycle multiaxial fatigue strength of components treated by surface induction hardening (SIH). Surface quenching following surface induction heating is simulated, taking into account the following features of the process: (i) electromagnetic and thermal fields, (ii) phase transformation, and (iii) the residual stress field resulting from the entire process. The fatigue strength of the specimens was simulated using Crossland and Dang-Van criteria; the field of the residual stresses and the fatigue characteristics of both the untreated material and the treated layer (martensite) are considered. Fatigue tests on smooth specimens were carried out to compare simulated results with experimental data. These tests yield information regarding the influence of the thermal treatment on material behaviour and strength, including microstructure evolution and mechanical characteristics, especially in fatigue. For this purpose, residual stresses were analyzed by X-ray diffraction before and after the fatigue tests. Fatigue crack initiation areas (at the specimen's surface or below) are predicted depending on the depth of the hardened material layer. The simulation of the fatigue strength at 2 Â 10 6 cycles is in good agreement with experimental results.
