A study was undertaken into the structure, the texture, the strength, and the creep of the
Cr16Ni15Mo3Ti type steel tubes cold-deformed to 20% strain that are used as the fuel
element shells for fast-neutron reactors. The tubes were found to have fibrous 〈111〉 and
〈100〉 textures along their axis. The preferred orientations 〈011〉 normal to the radial plane
and (011) and (112) normal to the plane tangential to the tube surface were determined.
The strength, the creep strength, and the rupture strength proved to be higher along the
tube axis. Qualitatively, this is attributed to a specific texture and the grain shape of the
material.
