英文摘要	The influence of ceramic shell mold with central heat radiation on the microstructures and stress rupture property of DD6 single crystal superalloy was studied. The results indicate that the mold with graphite center pillar could improve the uniformity of the temperature field and the temperature gradient during the solidification, and it could straighten the direction of heat flow. As a result, the primary dendrite arm spacing decreases, the size and the volume fraction of gamma-gamma' eutectic decline, the angle between the single crystal growth orientation and the [001] orientation decreases, so the single crystal superalloy achieves a longer stress rupture life.
