Full Description

These reference radiographs illustrate various types and degrees of discontinuities occurring in high-strength copper-base, nickel-copper, and related types of alloys.

These reference radiographs are reproductions of original radiographs that contain indications of discontinuities in sand-cast manganese-nickel-aluminum bronze-alloy plates. These discontinuities are representative of those found in narrow freezing range (formerly "high shrinkage" ), high-strength copper and nickel-copper alloys.

The two sets of reference radiographs consist of 56 radiographic reproductions ( 28 for each set) in 8 1/2 by 11-in. ring binders. In 1972, the number of categories was increased from five to six and the number of radiographic reproductions reduced from 37 to 28 for each set.
