采用原位红外热像技术研究了氮对Fe-18% Mn-0.6% C孪晶诱导塑性钢动态应变再结晶行为的影响。氮的加入影响了Portevin-Le Châtelier带的起始和应力-应变曲线上锯齿的特征形状。此外，氮的添加导致动态应变时效的临界应变的增加。
The effect of nitrogen on the dynamic strain again behavior of a Fe–18% Mn–0.6% C twinning-induced plasticity steel was investigated by means of in situ infrared thermography during tensile testing. The addition of nitrogen affected the initiation of the Portevin–Le Châtelier bands and the characteristic shape of the serrations on the stress–strain curve. Also, nitrogen additions resulted in an increase in the critical strain for dynamic strain aging.
