文摘The carbide growth behavior of MAR-M247 LC alloy was investigated by directional solidification and quench method. The carbide volume fraction, trapping and growth behavior were correlated with the growth rate.It was found that the carbide volume fraction decreased at slower growth rate.This decreasing was caused by lower solidliquid interface trapping ability at slower growth rate.
