The effect of superheating on the solidification in Al Si 16% alloy is investigated. It is showed that the amount and size of the primary silicon phase increased greatly after superheating of high temperature (>900 ℃). The latent heat and initial temperature of primary solidification also increased obviously after high temperature superheating (>900 ℃) by DSC analysis. By the way of X ray diffractometer, it is found that the atomic coordination number of Al Si 16% alloy is higher than pure Al at high temperature (>900 ℃) and less than pure Al at low temperature (<900 ℃). The peaks implied solid Si phase appeared on diffraction intensity cure of liquid Al Si 16% alloy after superheating of high temperature while they were absent in the case of low temperature superheating.

研究了不同过热温度对Al-Si16%结晶组织的影响,发现当过热温度超过900℃后,试样中的初晶硅尺寸与数目大量增加,共晶硅的尺寸变小。DSC分析表明,一定程度的过热增加了Al-Si16%的结晶潜热。液态X射线研究发现,在900℃以下,Al-Si16%的平均配位数比相同温度纯铝低,而在900℃以上,合金的平均配位数要高。1250℃温度过热后,合金熔体在液相线上方就已出现与硅晶态相对应的衍射峰。过热温度对结晶行为的影响可用Al-Si16%熔体中Al-Si原子团在较高过热温度下向Si-Si原子集团转化的机制来解释。
