Abstract: The heat conductor (HC) technique was applied to produce dummy turbine blades of medium size. Because of
their excellent thermal physical properties, graphite
and SiC were selected as the HC material. Thermal measurements showed that both the graphite and the SiC
HCs achieved a significant reduction in undercooling at
platform extremities. It was possible to reduce the average undercooling by approx. 19 K. Metallographic investigations revealed a remarkable reduction in stray
grain formation, providing clear evidence of the effectiveness of the HC technique for improving the quality
of single crystal components.
