By means of tensile stress variation during heating-cooling, applied in each consecutive cycle, performed up to progressively higher strains, the constrained recovery behaviour of a Fe-15.8 Mn-3.8 Si-12.3 Cr-4.7 Ni (mass. %) shape memory alloy (SMA) was reported. During each cycle, temperature was increased from room temperature up to 453 K and decreased to room temperature, while keeping the specimen to a constant strain. The variation tendencies of tensile stress, developed during heating-cooling, with increasing both the number of cycles and the constant strain applied per each cycle, was evaluated and corroborated with structural changes. These changes were related to the occurrence of stress-induced martensite the relief variations of which were revealed, as well, at structural and sub-structural level.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
