Abstract: The apparatus includes a machine for subjecting a test-piece of superplastic material to a tensile test using a mobile member entraining one end of the test-piece and exerting traction on the test-piece. The mobile member is subjected to successive displacements whose speed and duration are controlled. The force applied to the test-piece and its length are measured as a function of time.
