摘要: 對φ5mm的進口Al-1%Si合金棒材的段料在不同溫度下保溫12h,水淬處理.通過對不同條件下得到的再結晶組織進行對比研究,分析了該材料再結晶規律,提出了其優化熱處理工藝.結果表明:該材料原有的等軸晶組織轉變為塑性和導電性能良好的單晶組織.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.
