- 摘要:
- 论述控制冷却工艺生产奥铁体球铁的研究现状及特点,分析冷却速率和等温时间对奥铁体球铁生产的影响,通过控制冷却工艺制备了奥铁体球铁,并探讨了该工艺的应用前景。结果表明,奥铁体组织中存在少量的珠光体,抗拉强度达到了1 020 MPa,伸长率为4%。The research status and characteristics of controlled cooling process for the production of austenitic nodular iron were discussed. The influence of cooling rate and isothermal time on the production of austenitic nodular iron was analyzed. The austenitic nodular iron was prepared by controlling cooling process, and its application prospect was discussed.
