Sixteen digital reference images, previously only available as film reference radiographs (ASTM E192), are now available from ASTM International.
The images illustrate the types and degrees of discontinuities that may be found in precision investment castings. The reference images are created from castings in iron-based alloys, but are commonly used also for nickel and cobalt based alloys common in turbine engine components.
This 3 DVD set consists of the 16 digital files, software to load the desired format, and specific instructions on the loading process.
Disk one includes the install program, the ungraded plate of Discrete Discontinuities (including: Foreign Material More Dense, Cold Shut, Hot Tear, Cold Crack, Misrun and Core Shift), graded series for Foreign Material Less Dense in three thicknesses inch, 1/8 inch, 3/8 inch, and 3/4 inch, and graded series of Gas Holes for 1/8 and 3/8 inch.
Disk two includes the graded series for Gas Holes at 3/4 inch and for Dendritic Shrinkage at all three thicknesses. It also includes the ungraded plate of indications including Mold Buckle (positive and negative), Mold Ridge, Excess Metal in Cracked Core, and columnar and Mottled Diffraction Patterns.
Disk three includes graded series of Sponge Shrinkage for all three thicknesses as well as graded series of Shrinkage Cavity and Filamentary Shrinkage, both illustrated in 3/4 inch material.
The graded series each illustrate eight grades of severity. The images may be installed as 16-bit TIFF files or as DICONDE files and may be installed for negative or positive image polarity. The images may be installed at resolutions to match the effective resolution of various digital detectors in increments of 10 microns.
