固态压铸与普通压铸区别

压铸过程与普通液态压铸相似

  • 液态压铸:液态合金填充,凝固过程全部在模内。
  • 半固态压铸:半固态浆料填充,模具外开始模具内完全凝固。

关键:组织决定性能
半固态压铸 - 球晶
普通压铸 - 枝晶

半固态产品 - 坯料特点、微观组织特点

  • 50% 液相 - 50% 固相
50% liquid phase - 50% solid phase
  • 球状微观组织
Globular microstructure
  • 流体黏度高
High fluid viscosity
  • 平稳顺序充型
Steady sequential filling
普通压铸 - 枝晶组织
半固态压铸 - 球状组织
