Abstract A good selection of the thermomechanical processing parameters will optimize function alloying elements to get most mechanical properties in Advanced High-Strength Steels for automotive components, where high resistance is required passenger safety. As such, critical temperatures must be defined taking into account alloy composition, order effective schedules designed. These mainly inc...

Abstract Hot deformation tests of 5CrNiMoV steel were performed at temperatures 700 to 870 °C and strain rates 0.001 0.1 s −1 using the DIL 805D thermomechanical simulator. The critical volume fraction models Dynamic Recrystallization (DRX) constructed based on work hardening theory. results showed that DRX decreases with increasing temperature decreasing rate, which implies occurs easily highe...

A computational multiscale method is proposed to simulate coupled, nonequilibrium thermomechanical processes. This multiscale framework couples together thermomechanical equations at the coarse scale with nonequilibrium molecular dynamics at the fine scale. The novel concept of distributed coarse scale thermostats enables subsets of fine scale atoms to be attached to different coarse scale node...

The mechanical improvement and "self-protection" properties are mainly needed to develop weather-resistant steel materials. In this study, A588 was given thermomechanical treatment (hot-rolling) followed by a quench-tempering process. is modified adding 1, 2, 3 wt% nickel the primary alloy. Steel made using hot rolling process at 750 ℃ for 1 hour with 70% thickness reduction. sample heat-treate...

In general, the strength-to-weight ratio is a marked property of high- strength low-alloy steel. The coiling temperature an important process parameter in control and improvement final microstructure mechanical properties. this work, effect deformation on properties high Ti- V microalloyed HSLA steels were investigated using Gleeble 1500 TM thermomechanical processing simulator. samples austeni...
