研究了4032B铝合金活塞材料铸造工艺及变质处理工艺。结果表明,采用X变质处理后,铸件显微组织中没有块状初晶硅和层状共晶硅组织,力学性能也较变质前有了很大的提高。
The 4032B aluminum alloy piston material casting process and metamorphic treatment process were studied. The results show that there is no massive silicon and lamellar eutectic silicon microstructure in the castings after X modification, and the mechanical properties of the castings are also improved greatly compared with that before metamorphism.
