【摘要】 本文研究了连续电脉冲处理对共晶铝硅合金凝固组织的影响。结果显示,电脉冲处理后Al-12.5%Si共晶合金的凝固组织中出现了本应在过共晶成分的铝硅合金中才会出现的初生硅。X-射线能谱分析表明,电脉冲处理后α-Al枝晶中固溶Si含量降低。更多还原

【Abstract】 The effect of electric pulse treating on the solidification structures of Al-12.5%Si alloy has been investigated. The results show that nascent Si which should present in the hypereutectic Al-Si alloy appeared in the eutectic solidification structure after treated by electric pulse. X-ray energy spectrum indicates the composition of solid solution Si in α-Al decreases after treated by electric pulse.更多还原
