Directional solidification of single crystal blades under industrial conditions using the developed air-cooled casting method (2)
In order to better evaluate the directional solidification process, the dendrite microstructure was described by measuring the primary dendrite spacing (PDAS) in different regions on cross-section 4 and cross-section 9 of some blades [Figure 3(a) and (b)]. To do this, we use the relation PDAS =√(A/N), where A is the region being analyzed and N […]
Directional solidification of single crystal blades under industrial conditions using the developed air-cooled casting method (1)
In this paper, the effect of gas cooling on microstructure refinement of single crystal blades produced by DGCC gas cooling casting process was studied. The primary dendrite arm spacing (PDAS) reaches the highest value on the airfoil and the lowest value on the blade platform. However, when Bridgman’s method is used, the PDAS value changes […]
The Current State and Significance of Turbine Discs in the Gas Turbine Industry
