Characteristic Flow Behavior and Processing Map of a Novel Lean Si Spring Steel for Automotive Stabilizer Bars

The spring steel for automotive stabilizer bars has a great responsibility in that its quality directly affects the stability, safety, and comfort of vehicle operation. isothermal thermal compression behavior novel lean Si was used to manufacture an anti-roll bar investigated with DIL805A/D quenching dilatometer this research. A hyperbolic sine type constitutive model established, hot processing maps were produced evaluate experimental steel’s workability properties. results suggest dynamic recrystallization (DRX) preferentially occurs at low strain rate high temperature, while are susceptible strain. instability regions increase as increases. maps’ stable instable domains should be decided upon comprehensive analysis criterion, power dissipation efficiency, sensitivity index. optimum parameters various strains deformation temperature 1000–1150 °C 0.1, approximately.
