Induction heat treatment of a ISO C45 steel bar

Feb 01, 2006 · An experimental and numerical study was carried out on the induction hardening process of type C45 steel. The test pieces have been used both in the annealed and normalised states. The hardened depth and the microstructure of the samples were investigated through conventional microstructure and micro-hardness analyses. Interpretation of the Microstructure of SteelsFigure 44:Optical micrograph of a mixed microstructure of bainite and martensite in a medium carbon steel. The bainite etched dark because it is a mixture of ferrite and cementite, and the b / interfaces are easily attacked by the nital etchant used. The residual phase is untempered martensite which etches lighter because of the absence

Microstructural Features of Austenite Formation in C35 and

May 01, 2007 · In order to examine the evolution of the microstructure during continuous heating in C35 and C45 steels, a set of interrupted heating experiments was performed using a Bähr 805A/D dilatometer (Hüllhorst, Germany). Typical micrographs of the initial microstructures for C35 and C45 alloys are shown in Figure 3. The microstructures consist of ferrite and pearlite mixture with different phase Microstructure and selected properties of boronized Microstructure of boronized layer on C45 and CT90 steels were shown in Figure 3. The boronized layer on C45 steel (Fig. 3a) had a needle-like microstructure, wherein the needles have characteristic

Jul 08, 2018 · The steel C45 was quenched in water after one hour of austenitisation at 820 °C. Figure:Micrograph of a hardened steel (C45) The micrograph below also shows a martensitic microstructure of the 25CrMo4 steel. Figure:Micrograph of 25CrMo4. In principle, a steel contains considerably fewer carbon atoms than unit cells. Rotary friction welded C45 to 16NiCr6 steel rods Jul 07, 2021 · Medium carbon steel (C45) and Nickel chromium alloy structural steel for case hardening (16NiCr6) rods with 12 mm in diameters and 45 mm in length were used for the present study. The chemical compositions and mechanical properties of the base metals are presented in Tables 2 and 3, respectively. The microstructure of the C45 and 16NiCr6 showed both a ferrite and pearlite structure

Mechanical and microstructural testing of C-45 material

Jan 01, 2021 · In present exploration, tensile testing, microstructural analysis and dye penetration test (DPT) was done on C45 (AISI 1045) alloy. The main objective is to generate the weldability of C45 alloy. There was pre and post weld heat treatment (PWHT) on the C45 material. In the existing work, Gas Metal Arc Welding (GMAW) and Shielded Metal Arc Welding (SMAW) processes were used.
