Method for determining an elasticity modulus for metallic material by tensile testing, where the material has at least one precipitation phase distributed in a metallic matrix and also exhibits a non-linear stress/strain relationship within a region of substantially elastic deformation. The method is particularly distinguished by steps of - a first step (3) of loading the material to a limit stress (1) which corresponds to an expected maximum working load, and of thereafter removing the load from the material; - loading the material again at least once (4, 5, 6) to a working stress (2) which corresponds to an expected working load during use; - determining an elasticity modulus in a substantially known manner from the stress/strain relationship pertaining to the sixth loading (6). |
