| Abstract: | The first stage hollow turbine blades were taken as typical parts to research, The simulations of the temperature fields on blade, ceramic core and ceramic shell during directional solidification were investigated. The expend-behavior characteristic of ceramic at the course of solidification was analyzed. Locating model of ceramic cores was designed and presented. |
