摘要

分别用20钢和2036铝合金作为固相材料

用Al-13Si铝合金作为液相材料

探讨了在加热过程中

不同形态的固液界面对传热过程的影响。结果表明

在液相合金的固相层形成之前

固液界面的传热效果主要取决于固相材料传热特性;固液界面的接触情况对界面传热的效果产生较大的影响;在液相合金的固相层形成之后

固液界面的传热效果主要取决于液相合金固相层的生长过程所释放出来的结晶潜热;当固相合金发生界面熔化时

界面的熔化速度及结晶潜热将对固相的温度产生影响。

Abstract

Influences of the morphology of solid-liquid interface during the heating process were analyzed with the 20 steel and 2036 aluminum alloy as solid material and with the Al-13 Si aluminum alloy as liquid material.The experimental results show that before the solid layer of liquid alloy is solidified

the interfacial heating transferring is dependent on the characteristics of solid material.In addition

the contacted condition of solid-liquid interface plays a positive role in interfacial heating transferring effects.After the solid phase layer is solidified

the heating effect is dependent on the latent heat during solid phase layer growth.When the interface of the solid phase was melted

the melting speed of interface and latent heating exhibits a observedly role on temperature of the solid phase.
