| Abstract: | The effect of solidification rate on the microstructures of directionallysolidified superalloy DZ22 was studied with the help of a ZMLMC directionalsolidification apparatus which has a superhigh temperature gradient. The results showthat the size and shapes of Y', (Y Y') and MC change seriously with the increase in cool-ing rate. When the cooling rate is equal to 54.2K . s-1, Y' particles distnbute evenly;eutectic (Y Y') in group block and MC in block are distributed in the interdendriticzone. |
