摘  要:
通过定向凝固和计时电位法,结合电镜及计算技术,分别对La在Al-Si合金中的作用机制及La的扩散进行了研究。结果表明,由于La的扩散速度慢,有利于La的富集,而La的富集又对组织的细化具有重要的作用。

摘  要:
The directional solidification method and the chronopotentiometry, combined with SEM and computer, have been used to study La behavior in Al-Si eutectic alloys and to measure the diffusion coefficients of La in liquid Al-Si alloys. It is suggested that the diffusion of La is slower, which increases the segregation of La. The segregation of La makes great contribution to the fine mic-rostructure of Al-Si alloys.
