Abstract
Steels with high boron content are the most used material for the compact storage racks for used nuclear fuel. The influence of the concentration ratio of Ti/B and the cooling rate on the microstructure and hardness of the steel with a high content of boron was investigated. It is shown that the microstructure of steel is composed of particles of (Fe, Cr)2B and TiB2 , uniformly distributed in the ferrite matrix. Increasing the cooling rate leads to a decrease TiB2 sizes from 20 to 2 micrometers and to disperse of the eutectic ferrite + (Fe, Cr)2B and, consequently , increased the hardness.
