| 英文摘要 | The influence of directionally solidified process on porosity in cross-section transitions of dummy blade nickel-based superalloy DZ417G was investigated. It is found that the content of porosity at transition platform near the central runner is an order of magnitude higher than that near the heater. In a certain casting temperature range (1480 similar to 1580 degrees C), with the increase of casting temperature, the content of porosity at transition platform near the central runner increases at first and then decreases, and the temperature with maximum content of porosity is 1550 degrees C; however, in this casting temperature range, with the increase of casting temperature, the content of porosity at transition platform near the heater decreases a little bit. In a certain withdrawal velocity range (1 similar to 10 mm/min), with the increase of withdrawal velocity, porosity at transition platform near the central runner increases gradually; however the porosity at the opposite side part decreases. Based on these results, the relationship between casting temperature, withdrawal velocity and the content of porosity in transition platform dummy blade has been proposed. Besides, the influence of directional solidification process on the formation of porosity on the cross-section of the platform is mainly caused by the variation of temperature gradient of the solid-liquid interface. |
