Relaxation spectra were determined for a high chromium-high nickel vacuum cast stainless steel. The specimens were tested in the following three conditions: (1) as-received and solution heat treated, (2) nitrided 20 hours and solution heat treated, and (3) nitrided 40 hours and solution heat treated. No internal friction peaks were found in any of the experimental runs. There was no precipitation of nitrides during testing in the torsional pendulum. This was verified by an electron microscopic examination of the specimens after testing. Since there were no nitrides precipitated, no internal friction relaxation peaks were evident. / M.S.
