Appreciation of Crystal On the Mechanism of Eutectic Structure

论共晶结构的机理

When the pulling rates was low as 1 mm/ min, three-phase eutectic structure was observed and characteristic of directional solidification could be found in longitudinal section.

当下拉速率为1mm/min时，合金组织呈现三相共晶结构，纵截面有定向凝固趋势。

According to the results of DSC and microstructure analysis, the more Al content, the higher melting point of the alloy, but the more α phase dendrites, the less eutectic cementite.

从差示扫描量热分析和显微组织得出：随含铝量的增加，合金的熔点提高，α相枝晶增多，晶间的共晶体减少。

The results showed: in the as-cast white iron there was the enrichment of silicon between the eutectic cementite and pearlite.
