Optimum ductility is obtained with a ferritic matrix, so all NIBCO ductile iron is treated with a ferritizing annealing cycle.
由于最佳的韧性都是来自铁素基体，所以所有美国尼伯科球墨铸铁都经过铁素体退火韧化过程处理。 收藏。
Therefore, in thin section castings, for eliminating eutectic carbides and obtaining ferritic matrix, melts treated by re need high carbon content and hypereutectic composition.
在薄壁铸件中获得无游离渗碳体和铁素体基体的稀土球铁的关键是高碳过共晶原铁水。
The steels contain more than 0.08 % (mass percent) nitrogen in a ferritic matrix or more than 0.4 % (mass percent) nitrogen with an austenitic matrix were defined as high nitrogen steels.
铁素体基体中氮含量超过0.08%以上(质量分数)或奥氏体基体中氮含量超过0.4%(质量分数)以上的钢称为高氮钢。
The experimental result in this paper shows that the theory of elastic-plastic mechanics can be basically applied to spheroidal graphite cast iron with the matrix of ferritic-pearlitic.
