Méthode de détermination des caractéristiques de traction des matériaux métalliques superplastiques

ISO 20032:2013 specifies a method for evaluating the tensile properties of metallic superplastic materials which exhibit what is called "Fine-Grained Superplasticity", without significant work-hardening or dynamic microstructure evolution, by means of a tensile test at constant cross-head velocity, for flat-form test pieces, without an extensometer attached.
