Additive Manufacturing of Single Crystal Superalloy CMSX 4 Through Scanning Laser Epitaxy Computational Modeling, Experimental Process Development, and Process Parameter Optimization.This paper focuses on additive manufacturing AM of single crystal SX nickel based superalloy CMSX 4 through scanning laser epitaxy SLE.SLE, a powder bed fusion based AM process was explored for the purpose of producing crack free, dense deposits of CMSX 4 on top of similar chemistry investment cast substrates.Optical microscopy and scanning electron microscopy SEM investigations revealed the presence of dendritic microstructures that consisted of fine precipitates within the matrix in the deposit region.Computational fluid dynamics CFD based process modeling, statistical design of experiments Do.In our recent work Grujicic et al., Int.

E, and microstructural characterization techniques were combined to produce metallurgically bonded single crystal deposits of more than 5.A customized quantitative metallography based image analysis technique was employed for automatic extraction of various deposit quality metrics from the digital cross sectional micrographs.The processing parameters were varied, and optimal processing windows were identified to obtain good quality deposits.The results reported here represent one of the few successes obtained in producing single crystal epitaxial deposits through a powder bed fusion based metal AM process and thus demonstrate the potential of SLE to repair and manufacture single crystal hot section components of gas turbine systems from nickel based superalloy powders.
