Influence of hot plastic deformation and cooling rate on martensite and bainite start temperatures in 22MnB5 steel
Abstract: During hot stamping process, hot forming, cooling and phase transformations are performed in a single step As a matter of fact, multifunctional phenomena happen and affect each other Among these phenomena, martensitic and bainitic transformations have the greatest importance In the current research, the start temperatures of martensite and bainite of 22MnB5 boron steel have been measured in undeformed and 40% deformed conditions, and in various cooling rates from 04 °C/s to 100 °C/s by means of deformation dilatometer It is concluded that, reduction of cooling rate, could bring about an increase or decrease in M s and M f , depending on other phases formation before martensite Also, hot plastic deformation, hindered the martensitic transformation and decreased M f and M s especially at lower cooling rates, while B s increased Furthermore, the critical cooling rate, increased about 40 °C/s by applying 40% hot plastic deformation
