Conclusions

  1. 1.

    The radiation resistance of maraging steels is superior to that of pearlitic steels. After irradiation with an integral neutron flux of 8·1020N/cm2 at 70–100° the ductile-brittle transition temperature of the pearlitic steel rises from −80 to +100°, while that of the maraging steel remains below −80°. The changes in the strength, ductility, and toughness are smaller than in pearlitic steels.

  2. 2.

    The radiation resistance of maraging steel increases with the original strength after heat treatment and with the concentration of alloying elements causing an increase in strength during aging.
