摘要
研究了Ti-IF无间隙原子钢热轧、冷轧、退火(700、800℃)过程的析出行为与织构。该钢在700℃退火过程中形成的FeTiP析出颗粒降低了{111}织构强度,导致r值降低;而800℃退火过程中形成的析出颗粒提高{111}织构强度,强的{111}织构强度增加r值。700℃退火析出物主要为FeTiP,800℃退火析出物主要为Ti4C2S2;由于形成Ti4C2S2析出物,使C在再结晶退火过程中很容易从固溶体中析出而形成{111}织构,促使800℃退火时获得良好的成型性。
The precipitation behavior and texture formation during hot rolling, cold rolling and annealing （ at 700 ℃ and 800 ℃ ） have been studied in a Tieontaining interstitial freesteel. The presence of FeTiP in the 700 ℃ annealed steel and its absence in the 800 ℃ annealed material are eonsidered to be respon sible for the poor { 111} texture and low r in the former and strong { 111 } texture and high r in the latter. Annealing at 700 ℃ produces copious FeTiP type precipitates, while after annealing at 800 ℃ Ti4C2S2 precipitates form. Due to the formation of Ti4C2S2, C is easily taken out of the solid solution during re crystallization annealing and this results in better { 111 } texture formation and thus better formability in the 800 ℃ annealed material.
