  We have proposed and developed a new creep constitutive equation for Ni-base superalloys with good reproductibility under the conditions of high temperature low stress and low temperature high stress, good predictivity under the condition of high temperature low stress and middle temperature middle stress. In this paper, an application of a factor analysis for each parameter sets of the equation under the condition of 1100°C/137 MPa, 1000°C/245 MPa, 900°C/392 MPa, 800°C/735 MPa are discussed. In every condition, 2 to 4 factors are got by the analysis, and the tendency of factor loading shows the correspondence of each factor to each creep stage.
