【摘要】 白口铸铁的组织中含有相当数量的渗碳体,通常被认为难以进行塑性加工。本文的研究表明,在680～1100℃的温度范围内,白口铸铁可以进行热锻、热轧及温轧等压力加工变形。塑性加工能大大改善白口铸铁的铸态组织,这将扩大白口铸铁的使用范围。更多还原

【Abstract】 White cast iron contains a large amount of cementite which are considered to be the major element making hot-plastic deformation difficult. The investigation in this paper shows:In the range from 680°to 1100℃ white cast iron can be deformed through hot forging, hot and warm rolling. The worked metals have been improved greatly in structure than cast state. This may widen the use of white cast iron.更多还原
