Abstract

The subject of the application is a method for determining the life of a material resulting from the interaction of creep and fatigue, comprising the steps of: taking a sample of the tested material (m), carrying out an EBSD analysis of the tested material (m) in order to determine the density of necessary dislocations (GNDnorm), hardness (H) and material parameters, characterized in that the plastic deformation factor (ăp) is determined based on formula A, the life of the tested material (m) is determined by reading the expected life value for the point corresponding to the plastic deformation parameter (ăp) from the life curve of the reference material (w) obtained for the reference material (w) with a life cycle and shape corresponding to the tested material (m).
