研究了高强度无间隙原子（ Ｉ Ｆ） 钢的再结晶规律及退火条件对高强 Ｉ Ｆ钢性能的影响规律，从而找到一套适合现场生产条件的退火工艺参数，为高强 Ｉ Ｆ 钢的生产提供了理论依据
The recrystallization rules of high-strength interstitial-free (I F) steel and the influence of annealing conditions on the properties of high-strength I F steel were studied to find out a set of annealing process parameters suitable for on-site production conditions for the production of high-strength I F steel The theoretical basis
