Studies on creep-fatigue interaction behaviour of Alloy 617M
TL;DR: In this paper, the creep-fatigue interaction tests were conducted in air environment at a constant strain rate of 3'×'10−3 s−1 and strain amplitude of ± 0.4% with hold periods of 1'min, 10'min and 30'min at peak tension or compression at 973'K.

Creep Deformation Behavior of Inconel 617 Alloy in the Temperature Range of 650 °C to 800 °C
TL;DR: Inconel 617 alloy has been investigated through tests carried out in the temperature range of 650 °C to 800 °C under 95 to 350 MPa in this paper, with the primary creep rate decreasing to a minimum value, followed by a typical increase, which is either continuous at temperatures ≤ 700 °C or has an intermediate steady-state regime at 750 °C/800 °C.

Influence of temperature on multiaxial creep behaviour of 304HCu austenitic stainless steel
TL;DR: In this article, the effect of temperature on multiaxial creep behaviour of 304HCu stainless steel has been investigated and the multiaXiality was introduced by incorporating notches in smooth specimens.

Flow Behaviour of Modified 9Cr–1Mo Steel at Elevated Temperatures
TL;DR: In this paper, the flow behavior of modified 9Cr-1Mo steel at elevated temperatures was investigated and the yield strength and ultimate tensile strength were found to decrease with increase in temperature with a plateau in a intermediate temperature regime.
