| Abstract: | Ageneral relation between modulus of elasticity E and temperature T formetallic materials is obtained by means of the a phenomenological theory.A corrections of relationships between E and T for some metals at hightemperature are also given in terms of a fact that thermal stimulation.causes local plasic deformation. According to the statistital residualanalysis, good agreement between calculations and experiments is shown. |
