The results obtained show an important phosphorus effect on radiation hardening and embrittlement in the low-copper steels, an appreciable embrittlement after thermal segregation of phosphorus due to a change in fracture mode from cleavage to intergranular, and a radiation hardening and embrittlement of the same order of magnitude on the segregated steel for irradiation effect.
