auto. Normalized
met. normalizing (【技】将奥氏体化的工件保温一定时间,然后在空气或保护气氛中冷却转变成接近平衡状态的一种热处理工艺。正火的目的在于消除带状组织、网状碳化物,细化晶粒和珠光体组织,使组织均匀化,为淬火或球化退火做准备。低碳钢通过正火处理后,可提高硬度,避免切削加工时出现"粘刀"现象。珠光体型低合金耐热钢通过正火处理可提高强度、改善韧性。: ① The heat-treatment processes of steel parts include hardening, annealing, normalizing, spheroidizing annealing, stress-relief annealing and case hardening. 钢质零部件的热处理法包括:淬火、退火、正火、球化退火、去应力退火和表面硬化等。 ②Normalizing involves heating the steel parts to temperature of about 55 一 100°C above the critical range and cooling in still air. 正火的方法是将钢质零部件加热到临界温度以上约 55 ~ 100°C, 然后在静止的空气中冷却。)
