A bstract — Three series of tensile test pieces were produced using a nickel base partial denture casting alloy. For the first series induction heating was employed, for the second a resistance crucible, and for the third an oxy‐acetylene torch. All specimens were radiographed and a classification developed to indicate the radiographic soundness of each specimen. Radiographic soundness was subsequently related to the results obtained from mechanical testing.
