Abstract

The paper reviews the recent works concerning the Portevin-Le Chatelier (PLC) effect in Advanced High-Strength Steels (AHSSs) with a special attention to high-strength medium-manganese steels. Theories explaining the mechanism of the plastic instability phenomenon in steels with medium- and high-Mn contents were discussed. The relationships between microstructural effects such as TRIP (Transformation-Induced Plasticity), TWIP (Twinning-Induced Plasticity) and the PLC effect were characterized. The effects of processing conditions including a deformation state (hot-rolled and cold-rolled) and strain parameters (deformation temperature, strain rate) were addressed. Factors affecting the value of critical strain for the activation of serrated flow behavior in particular in medium-manganese steels were described.

摘要

本文回顾了近期关于先进高强度钢（AHSS）中Portevin-Le Chatelier（PLC）效应的研究工作，特别关注高强度中锰钢。讨论了解释中高锰含量钢中塑性失稳现象机制的理论。表征了诸如TRIP（相变诱发塑性）、TWIP（孪晶诱发塑性）等微观结构效应与PLC效应之间的关系。探讨了包括变形状态（热轧和冷轧）和应变参数（变形温度、应变速率）在内的加工条件的影响。描述了影响特别是中锰钢中锯齿状流变行为激活临界应变值的因素。
