Effects of Strain Rate on Tensile Deformation Behavior of Quenching and Partitioning Steel

摘要：

　　The effects of strain rate on the tensile deformation behavior of quenching and partitioning (Q&P) steel applied to the auto industry were investigated.The results indicated that the strength of Q&P steel raised with increasing strain rate.The variation of elongation which presented the trend of declining (10-4 s-1~101 s-1) followed by rising to the peak (8×101 s-1) then falling again (102 s-1~103 s-1),is mainly caused by the transformation from retained austenite to martensite,namely the TRIP effect.
