Effect of Temperature Cycling on the Rupture Strength of Some High-Temperature Alloys

Source

Cyclic temperature rapture tests were conducted on four different high- temperature alloys (S816, M252, 16-25-6, and A286). Specimens were subjected to a constant load and three different types of temperature cycles. The size of the specimens and the method of heating was such that thermal stresses were considered to be negligible. The results of the tests are compared with calculated rupture lives made using constant temperature rupture data and integrating the life expenditure over a complete temperature cycle. The calculated and actual test values correlate very well, although in general the actual values are somewhat lower than the calculated values.
