Numerical Simulation of Crack Condition in Forging Products of M50 Bearing Steel Based on Processing Map Theory

The microstructure of forged products significantly impacts their properties, and defects or carbide distribution are not visible to the naked eye. Isothermal compression tests on M50 steel with a Gleeble 3500 tester were conducted study behavior during forging. Tests examined hot deformation within temperature range 900–1200 °C strain rate 0.01–10 s?1. Power dissipation efficiency (?) flow instability (?), which crucial processing map parameters, employed analyze high-temperature steel. 3D determined optimum forging conditions, indicating that working should start at an initial 1050 higher 1 s?1, decreasing as increases. power displayed average value 0.43 0.1 s?1 1150 before reaching 0.8. Finite Element Method (FEM) simulated results, revealing ? ? distributions, confirmed observation matched parameters. This approach can effectively predict changes
