Abstract: A system and method are provided including an inclusion module to receive a powder sample from a powder source; a computed tomography equipment; a memory for storing program instructions; an inclusion processor, coupled to the memory, and in communication with the inclusion module, and operative to execute program instructions to: receive the powder sample; execute a computed tomography (CT) scan process of the received sample to generate a first dataset including one or more images; identify inclusions in the one or more images, via a segmentation process; reconstruct, via a reconstruction process, the identified inclusion into a 3D representation; measure the identified inclusion; mark the inclusions on one or more image slices from the 3D representations; and determine whether the powder source is contaminated based on the one or more marked images. Numerous other aspects are provided.

Abstract: The present disclosure relates to systems and methods useful for non-destructive evaluation (NDE) of molds and crucibles used in investment casting processes, including, without limitation, for producing aircraft engines, land-based turbine engines, and the like. According to one aspect, the present disclosure provides a system for non-destructive evaluation that includes a support, a 3D scanning device, and a computer component. According to another aspect, the present disclosure provides a method for non-destructive evaluation that includes the steps of: providing a system for non-destructive evaluation of a mold or crucible according to the present disclosure; securing a mold or crucible to the support of the system; and operating the 3D scanning device of the system in conjunction with the computer component in order to create a 3D structure difference map that indicates whether the mold or crucible falls within or outside a desired structural integrity parameter range.
