摘要
研究了以正火态粒状贝氏体为前组织的BZ11 空冷贝氏体钢,经亚温正火处理后组织和性能的变化。结果表明,经过正火处理的BZ11 钢,具有良好的强韧性,增加一道亚温正火后,其强韧性下降。
This paper deals with the microstructure and properties of subcritical normalized BZ 11 air cooled bainitic steel containing granular bainite have been studied.The results shown that good strength and toughness have been obtained after normalized,and it is lowered after subcritical normalized.
