摘要

液态金属的脉冲电场处理是改善金属凝固组织的一种新技术

其发展和应用与金属熔体结构及其相变动力学的研究进展直接相关。通过对电脉冲孕育处理试样的重熔试验

研究了铝熔体在该条件下的遗传特征。宏观组织观察表明一代遗传效应显著

按晶粒度度量的遗传因子在2.8～3.0之间;DSC分析揭示了脉冲电场下熔体结构的变异性

一定程度上验证了记忆载体———团簇在子代间的传递。

Abstract

The hereditary characterization of pure aluminum melt under pulse electric field was investigated by means of remelting experiment. Macrostructure observation shows that the first generation samples get remarkable heredity

whose genetic factor is in the range from 2.8 to 3.0 based on the measurement of grain size in casting structure. It is verified to certain extent that genetic carrier （cluster） among filial generations possesses transferability by analyzing the variability of aluminum melt under pulse electric field with DSC.
