"Prediction of Hardening Depth for AISI 1045 Specimen by High-Frequency Induction Process with Finite Element Analysis"
Abstract: A high-frequency induction hardening analysis method was established based on electromagnetic-thermal translate analysis (co-simulation). To apply the same conditions as that of the experiment to the high-frequency induction hardening analysis, the temperature-dependent material properties of AISI 1045 were entered. During cooling, the analysis results could be obtained by setting the cooling conditions of water. After the hardening depth of the high-frequency induction-hardened specimen was measured using a micro Vickers hardness tester, the hardening depth and hardening pattern were verified with a metallurgical structure. The experiment results were compared with the finite element analysis (FEA) results. The hardening pattern could be confirmed because AISI 1045 was heated to over 746°C, which was the A2 transformation point, and cooled to below 200°C. The FEA results could confirm the heating and cooling temperatures. In addition, the hardening depth was found to be similar to the hardened area. When AISI 1045 was heated over the A2 transformation point, its structure transformed from ferrite to austenite and it changed from a magnetic material to a non-magnetic material. The FEA of magnetic flux density and Joule heat density during heating revealed that high-frequency induction hardening is favorable for surface hardening.
