Positive and negative magnetostrictive amorphous ribbons have been locally current annealed under local stress to induce different anisotropies, which have been studied by observing the magnetic domains. In samples annealed under low applied stresses, the

Austenitic stainless steels have recently been used as reinforcing bars in special civil constructions in order to increase their expected life in corrosion environments. The complete mechanical characterization of two kinds of austenitic stainless steel rebars, 304LN and 316LN grades, obtained after hot and cold rolling schedules, was performed. Their mechanical properties and the influence on these of the rib region were obtained, as well as determining the fracture behaviour of these bars by means of their J–R curves. The experimental work was completed with the study of the corrosion behaviour of all the bars in a saline environment. All the results have been justified taking into account the fabrication method employed in each case.
