挤压及半固态等温处理对Al-30％Si合金组织的影响
Influence of extrusion and semi-solid isothermal heat treatment on microstructure in Al-30％Si alloy
摘要
Abstract
In order to obtain small, round primary silicon, the extrusion and semi-solid isothermal heat treatment was carried on to Al-SOiKiSi alloy. The average diameter and the nod-ularization of the primary silicon were measured by means of optical microscope and Image Pro Plus. The results indicated that extrusion deformation can significantly refine primary silicon. Both temperature and the holding time during semi-solid isothermal heat treatment have apparent influence on the microstructure of the alloys. The better microstructure can be obtained at about 640 ℃and the holding time about 10 min.关键词
