N2 - Creep rupture properties of heat resistant alloys with carbide or carbide and gamma prime precipitates were investigated in the temperature range from 900 degree C to 1050 degree C in He and reducing gas atmospheres. Degradation of rupture strengths took place due to decarburization in He at temperature above 1000 degree C. In the alloy which was strengthened mainly by gamma prime , solutioning of gamma led to degradation of strength, but to restoration of rupture ductilities. A new method to predict rupture life and steady state creep rate from 0. 2% proof stress is proposed.
