The fracturestress of DP microstructure increased with the increase of displacement speed, and the microcrack density increased with the decrease of displacement speed.
双态组织的断裂应力随加载速度的上升而增加,微裂纹面密度随加载速度的增加明显下降;

The local cleavage fracturestress is mainly determined by the length of the critical microcrack.
