As the reduction increased, changes in the elastic constants resulted in a steadily increasing orthotropy, which was clearly shown by Poisson’s ratio and acoustic birefringence. Although optical metallography and hardness measurements showed that partial or full recrystallization is attained after annealing at 600 °C and 700 °C, the ultrasonic measurements revealed that a high level of orthotropy remains.Linton CarvajalMaría SosaAlfredo ArtigasNelson LucoAlberto MonsalveMDPI AGarticleultrasoundTWIP steelelastic constantsPoisson’s ratiobirefringencecold rollingTechnologyTElectrical engineering.
