Abstract
THE elevated temperature embrittlement induced in austenitic steels by neutron irradiation is now well known1,2. Characteristic features are the intergranular mode of fracture in a tensile test and the marked reduction in the non-uniform elongation. Barnes3 has reported work by Pfeil and Barton which suggests that the (n, α) reaction of thermal neutrons with the boron-10 in the steel is responsible.
