摘　　要：研究了汽车用热镀锌高强度IF钢在不同退火工艺下析出物的形貌和分布特征。结果表明,无论是热轧还是经过不同退火工艺处理,其析出物中存在TiN、TiC、NbC和Fe(Ti+Nb)P等。退火过程中,不论保温时间的长短,退火温度的高低,其析出物均比热轧板中的析出物多。The precipitates morphologies and distributions of hot dip galvanized high-strength IF steel were investigated. The results show that the precipitates of the steel include TiN, TiC, NbC, Fe （Ti＋Nb）P and so on no matter the process of hot rolling or annealing. And the precipitates amount of the steel after annealing is more than that of the hot-rolled steel plate no matter holding time or annealing temperature during the annealing process.
