Abstract
A method of fabricating a turbine engine part, the method including fabricating an ingot out of ceramic material of eutectic composition by performing the Czochralski process including putting a seed of the ingot that is to be obtained into contact with a molten bath of a mixture of eutectic composition in order to initiate the formation of the ingot on the seed, the mixture including at least two ceramic compounds; drawing the ingot from the molten bath while imposing on the ingot that is being formed a drawing speed less than or equal to 10 mm/h together with rotation at a speed of rotation less than or equal to 50 rpm; and machining the ingot as fabricated in this way in order to obtain the turbine engine part.
