用法例句

    Series impact tests were carried out to measure the series impact work done to a 400?MPaclass supersteel which was supplied through controlled rolling and cooling rate accelerated with trace element Nb contained, thus giving a brittle transition temperature curve.

    以微Nb处理控轧控冷工艺生产的400MPa级超级钢为研究对象,采用"系列冲击实验法"测定系列冲击功,绘制出脆性转变温度曲线·按综合能量法及断口形貌,确定出脆性转变温度为-80℃,并与相同化学成分、普通方法生产的钢板的脆性转变温度加以比较,对这一温度降低的原因进行了分析·分析结果认为,脆性转变温度降低、低温韧性的改善是化学成分、微观组织、轧制工艺综合作用的结果·钢中S、P、Si含量低有利于脆性转变温度的降低、微量Nb的存在有利于脆性转变温度的降低;晶粒细化,亚晶强化是试验钢脆性转变温度降低的组织原因;控轧控冷工艺的采用是降低脆性转变温度的工艺因素
