Abstract
IT has been known for some time that neutron irradiation at ambient temperatures produces increases in the proof and ultimate tensile stresses and reductions in ductility of austenitic steels in room temperature tensile tests1. These changes in properties result from the interaction of dislocations with the vacant lattice sites and interstitial atoms produced by fast neutron-atom collisions and are recovered on testing at temperatures of about 500° C due to annihilation of the point defects2.
