The same DP steel and TRIP steel component parts of the mechanical properties compared

DP steel has high strength, but because of the phenomenon of transformation induced plasticity, TRIP steel has more excellent mechanical properties. (2) to B as the main second phase of the TRIP steel-hardening capacity is far less than the M for the second phase of the DP steel. In addition, changes to the M to further reduce its work-hardening capacity. (3) For the DP steel and TRIP steel, BH value of the air mass not only by the Coriolis effect. Also affected by the impact of elimination of internal stress. (4) DP steel during deformation stored in the large internal stress, the BH value is negative after baking. TRIP steel at low strain is within the scope Korotkoff play a leading role in air mass, the BH value increases with the deformation and then decreased, but the internal stress increases with the strain in high strain conditions, the BH value is eventually reduced is negative.
