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.

The paper presents possibilities of controlling temperature field distribution in inductively heated charge. The change of its distribution was obtained using the sequential one-, two-, and three-frequency heating. The study was conducted as a multi-variant computer simulation of hard coupled electromagnetic and temperature fields. For the analysis, a professional calculation software package utilizing the finite element method, Flux 3D, was used. The problem of obtaining an appropriate temperature distribution in the heated charge of a complex shape is very important in many practical applications. A typical example is hardening of gear wheels. For such an application, it is necessary to obtain (on the surface and at a desired depth) an uniform temperature distribution on the tooth face, top land and bottom land of the gear. The obtained temperature should have proper distribution and value. Such a distribution is very difficult to achieve.Keywords: induction heating, computer simulation, electromagnetic field, temperature field W artykule przedstawiono możliwość kształtowania rozkładu pola temperatury w nagrzewanym indukcyjnie wsadzie. Zmianę rozkładu temperatury uzyskano wykorzystując sekwencyjne nagrzewanie jedno-, dwu-i trój-częstotliwościowe. Badania przeprowadzono jako wielowariantową symulację komputerową silnie sprzężonego ze sobą pola elektromagnetycznego i pola temperatury. Do analizy wykorzystano profesjonalny pakiet obliczeniowy Flux 3D wykorzystujący metodę elementów skończonych. Problem uzyskania odpowiedniego rozkładu temperatury w nagrzewanym wsadzie o złożonej geometrii jest bardzo istotny w wielu zastosowaniach praktycznych. Typowym przykładem jest hartowanie kół zębatych. Dla takiego zastosowania wymagane jest uzyskanie równomiernego na powierzchni i na zadanej głębokości zęba i wrębu rozkładu temperatury o określonej wartości. Uzyskanie tak zdefiniowanego rozkładu jest bardzo trudne.

“…Induction melting allows the melting temperature of aluminium to be reached within a short time. In molten metals, induction phenomena create several harmonic or periodical electromagnetic fields resulting in the formation of temperature and flow fields [16,17]. These flow fields enable stirring of molten composites without any mechanical stirrer.…”

Introduction of TiB 2 reinforcements into aluminium matrices allows composites to be obtained that exhibit excellent mechanical properties and good wear and corrosion resistance. These composites find applications in the automotive, aerospace and marine industries. In the present work, the in situ synthesis of ultrafine TiB 2 particulates in an aluminium matrix was accomplished by reaction synthesis of TiB 2 using K 2 TiF 6 and KBF 4 (in 120% excess to the stoichiometrically needed) fluxes in pre-melted aluminium. Composites were prepared with different concentrations of TiB 2 in (2.5, 5 and 10 wt %) in an aluminium matrix. The holding time of the molten composite in an induction furnace was varied from 10 min to 50 min. The in situ formation of TiB 2 reinforcement and its distribution in cast aluminiummatrix composites was analyzed based on microstructural studies, microhardness measurements and wear tests. The exothermic reaction between the halide fluxes starts after 10 min of holding time and completes before 20 min of holding time. The dominant phase was TiB 2 after 20 min of holding time, while the formation of Ti 3 B 4 was observed as the holding time was extended. The distribution of the reinforcing phases was studied by analyzing the scanning electron microscopy (SEM) images. An optimum holding time (20 min) of the composite melt was determined based on the dominant wear mechanism, microhardness, and phase composition of the composites.
