研究了冷轧变形量和退火温度对孪晶诱导塑性钢力学性能的影响。结果表明，随着冷轧压下量的增加，未再结晶区纳米级孪晶密度高的强化效果增强。另外。延展性也随着退火温度的增加而增加。因此，利用大的冷轧压下量和随后的退火处理的部分再结晶区被建议作为一种有效的方法，获得亚微米晶粒的T4S钢具有良好的强度和塑性的组合。(C)2009爱思唯尔有限公司版权所有。
The effects of cold rolling reduction and annealing temperature on the mechanical properties of twinning induced plasticity (TWIP) steel have been investigated. The results indicated that the strengthening effect of unrecrystallized areas with a high density of nano-scale mechanical twins increased with increasing cold rolling reduction. In addition. the ductility also increased with increasing annealing temperature. Therefore, utilization of large cold rolling reduction and subsequently annealing treatment in the partial recrystallization region was suggested as an effective method to obtain submicron grained TWIP steel with an excellent combination of strength and ductility.
