Abstract
A nondestructive inspection method 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 and the second inspection standards. The first inspection standard includes a first crack, induced by at least one of a thermal shock and a thermal stress. The second inspection standard includes a second crack, induced by at least one of the thermal shock and the thermal stress. At least one of the thermal shock and the thermal stress introduced during a sintering operation for the first inspection standard is different than at least one of the thermal shock and the thermal stress introduced during the sintering operation for the second inspection standard. The first crack and the second crack are different.
