Abstract Directional solidification technique was used to determine the effect of Ce on the solidification structure of low-sulphur 16Mn steel: The results show that addition of Ce increases the primary dendrite arm spacing and decreases the secondary dendrite arm spacing, the width of Columnar region, the size of equiaxed grains and the degree, of micro-segregation of Mn. This technique is expected to be used to reduce the detrimental influence of impurity particles on solidification structures.
