Abstract
The solidification behaviour of the single crystal superalloy CMSX-6 has been investigated using directional solidification technique. The longitudinal sections of the quenched samples were taken to identify the solidification structure. The experimentally determined solidification diagram gives the relationship between solidification structure and process parameters. The analysis of the transverse sections yields the solidification sequence and the solid fraction against the temperature decrease. The dendrite spacing was described as a function of solidification parameters.
