补充资料:球墨铸铁
      析出的石墨呈球形的铸铁。球状石墨对金属基体的割裂作用比片状石墨小,使铸铁的强度达到基体组织强度的70~90%,抗拉强度可达120kgf/mm2,并且具有良好的韧性。球墨铸铁除铁外的化学成分通常为:含碳量3.6~3.8%,含硅量2.0~3.0%,含锰、磷、硫总量不超过1.5%和适量的稀土、镁等球化剂。
  
  球墨铸铁生产工艺简单,铸造性能比铸钢好(但比灰口铸铁差),成本低,因此,被广泛用来制作受力复杂,对强度和韧性以及耐磨性要求较高的零件,如曲轴、齿轮、高压缸、汽车底盘零件等。20世纪70年代全世界的球墨铸铁管的年产量达数百万吨。中国古代铸铁中亦有球状石墨的组织(见冶金史)。
