Kind Code:
A1
Abstract:
Provided are a neutron absorbing material and a method for preparing same, wherein the neutron absorbing material is a steel comprising 0.1 to 2.5 wt% of Gd and/or 0.3 to 0.8 wt% of B, and further comprising 4.0 wt% or less of Mo (including 0 wt%), 6.5 wt% or less of W (including 0 wt%), 0.4 wt% or less of N (including 0 wt%), 16 to 34 wt% of Cr, 0.1 wt% or less of C (including 0 wt%),and Fe, and two phases of austenite and ferrite are admixed in the microstructure of the steel and an equivalent index value of the neutron absorbing material (PREN = Cr + 3.3(Mo + 0.5W) + 30N) reaches 30 or more. The neutron absorbing material according to the present invention has excellent strength, corrosion resistance, and processibility.
