中文摘要	研究了粒状贝氏体对超低碳含铜时效钢粗晶热影响区(CGHAZ)冲击韧性的影响.结果表明,粒状贝氏体中M-A岛的含量和尺寸对超低碳含铜时效钢CGHAZ的冲击韧性有显著影响.当M-A岛的数量少、尺寸小(其体积分数小于3%,尺寸小于1 mum)时,粒状贝氏体对CGHAZ的冲击韧性影响不大;当M-A岛的数量多、尺寸大(其体积分数大于3%,尺寸大于1 mum)时,CGHAZ的冲击韧性显著下降.通过降低钢中的碳及碳化物形成元素的含量可减少CGHAZ中粒状贝氏体的数量,从而提高钢的CGHAZ的冲击韧性.
英文摘要	The effect of granular bainite on impact toughness of CGHAZ of Ultra-low carbon copper-bearing age hardening steel was studied. The result showed that the quantity and dimension of M-A islands in granular bainite has a great effect on impact toughness of CGHAZ of ultra-low carbon copper-bearing age hardening steel. There is no visible effect on impact toughness when the amount of M-A islands is under 3 percent arid the dimensions of M-A islands less than 1 /nm. But impact toughness is decreased greatly when the amount of M-A islands exceeds 3 percent and the dimensions of M-A islands exceed 1 fim. The content of granular bainite is decreased with the de-crease of carbon and carbide forming elements, and the impact toughness of CGHAZ of the steel is increased at the same time.
