Texture in stainless steel welds: an ultrasonic study

Abstract

We studied texture effects in five AISI-316 stainless-steel welds. We measured nine independent ultrasonic velocities along the weld's principal axes. These velocities reveal a strong texture different from the 〈0 0 1〉 fibre-type usually attributed to these materials The texture is independent of delta-ferrite content and must contain a strong 〈110〉 component related to the f c c monocrystal elastic constantC′=(C11−C12)/2. A postulated ideal (0 0 1) [1 1 0] plate-type texture explains the range of measured longitudinal and transverse sound velocities, but not their detailed values.
