Microstructural features were revealed using light microscopy and scanning electron microscopy techniques. The rest of the properties required were calculated using the JMatPro software.

The final experiment was carried out using a thermo-mechanical simulator under conditions of multistep deformation and isothermal holding of the steel at 400C. The effects of the cooling rate and deformation at temperatures of 900 and 1,050C on the phase transformation behaviour and microstructure were explained. The temperatures of phase transformations were found using the JMatPro.

Transformation temperatures were calculated by means of the JMatPro. The major tests consisted of controlled cooling of undeformed or plastically deformed austenite using the dilatometer within the cooling rate range of 2-0.5C. Martensitic microstructures with a controlled fraction of retained austenite have. This experimental heat treatment led to a martensitic microstructure with retained. The equilibrium temperatures of and and phase composition of the investigated steel were initially calculated whereas critical temperatures of and as well as the decomposition of retained austenite were determined upon heating. Ferritic, bainitic and martensitic phase transformations are investigated in detail in respect of their temperature range forming and microstructures produced under various conditions of both continuous and isothermal cooling. the predicted MS was compared with that from JmatPro and several ML methods. The Ms temperature of 24CrNiMo alloy can be simulated using the relationship between martensitic transformation and the hardness module in the Jmatpro software. In thermodynamic models, the martensite transformation starts when the. Abstract : The work deals with dilatometric studies of a new-developed advanced high-strength bainitic 3Mn-1.5Al steel. 2 and fig.3 that the martensitic phase of the alloy steel is precipitated in the rapid cooling condition.
