摘要: Abstract The severe plastic deformation of a Twinning Induced Plasticity (TWIP), 0.61C–22.3Mn–0.19Si–0.14Ni–0.27Cr (wt%) steel by Equal Channel Angular Pressing (ECAP) at elevated temperatures was used to study the mechanism as function accumulated strain and processing parameters. relationship between microstructures after different schedules ECAP 200, 300 400 °C, hardening behavior mechanical properties studied. best balance strength ductility (1702 MPa 24%) found two passes 400 °C 300 °C ECAP. It due formation microbands twins in microstructure. twinning observed all except one pass 400 °C. important finding ultrafine grains. Moreover, stacking faults were subgrains with size 50 nm. is also worth mentioning nano-twins within micro-twins same time. that schedule affects dislocation substructure bands, cells, subgrains, variants that, turn, influence strain-hardening properties.
