试验研究得出 ,加入过量的Nb( 0 .2 % )导致Ti+Nb处理的高强IF钢板的连续退火再结晶延滞 ,在合适的Ti含量下 ,钢中Nb处于固溶状态时 ,有利于再结晶进行
The experimental results show that the addition of excessive Nb (0.2%) leads to the continuous annealing recrystallization delay of the Ti + Nb-treated high strength IF steel plate. When the content of Nb in the steel is in the solution state under the suitable Ti content, Crystallization
