Effect of Neutron Irradiation on Materials Subjected to Multiaxial Stress Distributions. Quarterly Progress Report, April 1-June 30, 1963

Results are reported for tensile and notched tensile tests on unirradiated and irradiated A-302B steel. The tensile results indicate that neutron irradiation decreases the uniform strain, increases the yield point, and decreases the strain hardening. The notched tensile results showed an increase in the ultimate tensile strength with irradiation. (D.L.C.
