Single-Crystal Manufacturing Technology

​

Single-crystal (SC) turbine blades are produced through carefully controlled directional solidification, in which the solidification front progresses through the molten superalloy under a controlled thermal gradient. The objective is to eliminate transverse grain boundaries and develop a single, continuous crystal structure throughout the component. Two important approaches to controlling this solidification process are the conventional Bridgman method and the more advanced Liquid Metal Cooling (LMC) method. While both technologies are used to produce directionally solidified (DS) and single-crystal (SC) components, they differ primarily in the way heat is extracted from the mold and the thermal gradient is maintained during solidification
