Abstract
A method for nondestructive testing includes steps of: (1) forming a first inspection standard using a metal injection molding process; (2) forming a second inspection standard using the metal injection molding process; and (3) creating a reference library that includes the first inspection standard and the second inspection standard. The first inspection standard includes first voids that are induced by a first set of conditions of a sintering operation and a hot isostatic pressing operation of the metal injection molding process. The second inspection standard includes second voids that are induced by a second set of the conditions of the sintering operation and the hot isostatic pressing operation. At least one of the conditions in the second set of the conditions is different than at least one of the conditions of the first set of the conditions. The first voids and the second voids are different.
