摘　　要：研究了变形温度及变形量对FH40高强度船板钢再结晶行为的影响规律。结果表明:试验钢变形量在20%~40%时,形变奥氏体处于部分再结晶区,温度的变化直接影响再结晶数量和晶粒尺寸。FH40高强船板钢发生完全再结晶所需的变形温度为1000℃、变形量为40%,此条件下变形下进行完全再结晶区轧制,获得细小、均匀的奥氏体晶粒。The effect of temperature and deformation on recrystallization behavior of FH40 high strength ship plate steel was studied.The results show that the deformed austenite is in the region of partial recrystallization when the deformation is between 20%and 40%,and the change of temperature directly affects the amount of recrystallization and grain size.The results show that the deformation temperature of FH40 high strength ship plate steel for complete recrystallization is 1000℃and the deformation is 40%.Under this condition,fine and uniform austenite grains can be obtained by rolling in the complete recrystallization zone.
