摘要
实验用ＨＱ钢的控轧控冷实验表明，典型组织为多边形铁素体＋粒状贝氏体。终轧温度、终冷温度和冷却速度等工艺参数对钢材的组织性能有很大的影响，可以通过各参数的合理组合，在提高强度的同时又提高韧性。
Controlled rolling and controlled cooling experments of a HQ steel showed that typical microstructure consists of polygonal ferrite+granular bainite. Processing parameters of controlled rolling and controlled cooling,such as finished rolling ternperature,finished cooling temperature and cooling rate,have great effects on microstructures and mechanical properties of steel . Streng hening as well as duitilty improvement could be achieved by reasonable combination of the processing parameters.
