929钢中的相和相变观测
Observation and Measurment of the phase and phase Transformation in Alloy Steel 929
-
α树枝晶发达而细小，二次枝晶臂间距显著减小；硅相和其他晶间相变为球状或细短条状且均匀弥散分布在α枝晶的晶界上；
Silicon phase and other intercrystalline phases are transformed into spheroid or slim short shapes , and uniformly distributed on the interdendritic zone ;

经钠盐精炼和0.2wt%RE变质后，硅相和其它晶间相变为球状或细短条状，均匀分布在晶界上；
After purified by sodium salt and modified by 0.2wt % RE , silicon phase and other intercrystalline phases are transformed into spheroid or slim short shapes , and uniformly distributed in the grain boundary .
