The influence of Gd additions on the microstructure and performance of rolling of Gd containing stainless steel was investigated by various microstructural characterization techniques. This work was conducted as a key step toward the development of Gd containing stainless steel for spent nuclear fuel applications. The Gd containing stainless steel was observed to solidify in a manner similar to a binary eutectic system. Small gas tungsten arc melt buttons were prepared to produce Gd containing stainless steel with Gd levels from 0.5-3 wt.% Gd. Electron microprobe measurements showed that Gd is essentially insoluble in the austenite/ferrite matrix. All of the alloys formed an interdendritic intermetallic, and the amount of the intermetallic phase increased with increasing Gd concentration. The interdendritic intermetallic behavior is similar to a simple binary eutectic in several ways. Hardness increased with increasing Gd concentration due to the formation of the intermetallic.
