Investigations into the effect of interruptions on the static creep test
To determine creep curves, creep tests are often run in a discontinuous manner. The question arises as to the accuracy of results so obtained, in view of the large number of thermal and mechanical manipulations which need to be carried out. In this project, alloy HP40Nb was tested at 1000 C. Results for relatively long stress cycles differed very little from those in the corresponding discontinuous test, whereas short cycles brought about a marked decrease in life. From the two cases it can be concluded that in the late tertiary portion of the curve, interruption should be avoided.
