本文介绍了用Larson-Miller、Manson-Haferd、Orr-Sherby-多恩法和基图法对250多幅蠕变断裂图进行外推分析的结果。它建立了外推计算，而不是内插的使用可能会导致预测误差的2 - 4倍的增加。分析了预测误差增加的原因和消除的可能性。
Results of extrapolation analysis of over 250 creep-rupture diagrams by the Larson-Miller, Manson-Haferd, Orr-Sherby-Dorn methods and the base diagram method are presented. It is established that the use of extrapolation calculations instead of interpolation ones may lead to a two-fourfold increase in prediction errors. The reasons for a considerable increase in prediction errors and possibilities of their elimination are analyzed.
