| 摘 要： | 在实验室加工了具有不同稀土、钛和铌含量的冷轧搪瓷钢板，测定了钢板的再结晶温度和模拟退火后钢板的成形性能，并观察了其金相组织，分析了钢中的第二相粒子。结果表明，在单加稀土、复合添加稀土 钛或稀土 钛 铌的3种钢中，单加稀土的钢再结晶温度最低，而含稀土 钛 铌的钢再结晶温度最高；经高温退火后，含稀土 钛 铌钢的伸长率和r值在3者中最高，达到了超深冲(即EDDQ)级别。

| Abstract: | The cold-rolled enamel sheets were manufactured in laboratory with different content of RE, Ti and Nb, and the recrystallization temperatures, tensile strength were measured after simulation annealing, the microstructure and precipitates were examined. The results show that the recrystallization temperature of steel containing RE is the lowest, while the steel cantaining RE+Ti+Nb presents the highest recrystallization temperature. After annealing at high temperature, the steel cantaining RE+Ti+Nb has extra-deep drawability quality (EDDQ). |
