摘要

采用钢及Al-10Si合金研究其半固态坯料加热时

液相温度与固相颗粒半径对热传导行为的影响。试验发现

液相温度和固相颗粒半径对固相传热效果有影响

且固相颗粒半径的影响程度会受到液相温度的制约;固相升温状态主要取决于固-液两相区的温度场的传热效果。

Abstract

Influences of liquid temperature and the solid particles radius on the heat transfer behavior in solid state were analyzed by heating steel and Al-10Si alloy semi-solid billet samples.The results reveal that liquid temperature and the solid particles radius have olvious effects on solid-phase heat transfer

and the solid phase particle radius is constrained by the liquid temperature.Solid phase heating state is mainly depended on the heat transfer effect of the temperature field in the solid-liquid two-phase region.
