Al-Si合金挤压棒材再结晶组织演变

Recrystallization Microstructure Evolution of Al-Si Squeezing Bar

    摘要
  • 摘要: 对φ5mm的进口Al-1%Si合金棒材的段料在不同温度下保温12h,水淬处理.通过对不同条件下得到的再结晶组织进行对比研究,分析了该材料再结晶规律,提出了其优化热处理工艺.结果表明:该材料原有的等轴晶组织转变为塑性和导电性能良好的单晶组织.

     

    Abstract: Al-1%Si segments with 5 mm in diameter were held at different temperatures for 12 h and quenched. The recrystallization mechanism of the material was investigated by contrasting recrystallization texture after different-temperature heat treatment. An optimal heat-treated process was proposed, by which the original tissue with orbicular crystals of the material can be transformed into single crystals with high extended rate and electrical conductivity.
