Title

Presentation of Creep Data for Design Purposes

Description

This program was conducted to obtain additional and comparative creep data, to compare creep data from several sources, and to recommend what values to present and in what form to present creep data for design purposes.

Conventional long time creep tests were performed on A-286 at 1200°F and 1500°F; A110AT at 800°F and 1000°F; and Unimach 2 at 600°F and 900°F for purposes of comparing with existing similar data. Conventional creep tests were performed on Rene' 41 at 1250, 1400, 1550, 1700, 1850 and 2000°F.

Data were analyzed and are presented in the form of activation series equations. Nomographs were derived for each material.

Cyclic creep tests were performed on Rene' 41, in which both stress and temperature were cycled. Cyclic data were found to be comparable to the constant stress constant temperature data.
