Abstract
The current paper outlines the concept of the constitutive equations o f the 'one-parameter model' describing the inelastic mechanical behavi or of metals. It concentrates on the version developed for a high temp erature alloy, INCOLOY alloy 800H(1), characterized by a time dependen t evolution of precipitates. The way in which this constitutive equati on models the behavior of the alloy taking in due consideration the pr ecipitation and ripening of carbides is discussed. Constant strain rat e and creep test results for alloy 800H are used as guiding data for t he calculations.
