Abstract

In Austenitic claddings of pressure vessel steel columnar grains with a 〈100〉-fiber axis oriented perpendicular to the surface have been previously observed. The fiber axis is parallel to the steepest temperature gradient. Since high temperature gradients also exist in the plane of cladding, preferred orientation should be found there.This was proved with {111}- and {220}-pole figures taken of the cladding in addition to {200}-pole figures. From these pole figures it could be concluded that the cladding has a {100} 〈110〉-texture. The sharpness of the texture decreases from the surface of the cladding toward the base material.Low values of Young's modulus measured in the cladding could be explained by comparing the texture with single crystal data of Young's modulus of Ni.
