Radiation Effects on the Mechanical Properties of SA 508 Cl.3 Forging


This paper presents preliminary results of an ongoing research program that the Italian Committee for Research and Development of Nuclear Energy and Alternative Energies (ENEA) started in the framework of the previous Nuclear Energy Plan.

A total of 25 tension tests, 162 Charpy tests, 56 KId tests, 30 KIc (or JIc) tests, and 17 crack-arrest tests have been performed on unirradiated and irradiated materials. Results are reported in this paper.

Additional tests are planned for irradiated specimens, including 19 tensile tests. 20 KId tests, 50 KIc tests, and 9 crackarrest tests.

This paper also reports on comparisons among transition-temperature shifts measured and expected on the basis of some of the best-known empirical prediction equations.
