| Abstract: | With the elastic and plastic deformation of the steel X8Mn16, respectively, a stress or deformation induced transformation of the fcc γ-matrix lattice into the hex. ϵ-martensite occurs, being connected with anisotropic changes in length, and leading to a decrease of the apparent elastic modulus of the alloy. A further investigation shows it is obviously the question of the result of the strain-memory effect, until now not yet being observed with iron alloys. Similar anisotropic changes in length can be taken into account with all pure metals and alloys, the martensitic transformation of which turns out under the influence of an outer uniaxial stress. |
