摘要：
Known parametric methods and a modified base diagram method were used to analyze extrapolation results for creep rupture diagrams of heat-resistant steels. Two model alternatives are examined: viz when the hypothesis of the "unified" curve is valid and when its application leads to significant errors in prediction of creep strain processes. The efficiency of proposed procedures and their advantages over other approaches are demonstrated.
