Long-term creep properties of Ni-based 21Cr-18Fe-9Mo superalloys
Science and Technology of Advanced Materials: Methods, 2023 Tensile properties and creep rupture strength were evaluated for Ni-based 21Cr-18Fe-9Mo superalloy plate and bar products used for gas turbines. Tensile tests at room temperature to 1000°C and creep tests at 700°C to 1000°C were performed in accordance ...

Creep Ruptures in Heterogeneous Materials [PDF]
Physical Review Letters, 2005 We present creep experiments on fiber composite materials with controlled heterogeneity. Recorded strain rates and acoustic emission rates exhibit a power law relaxation in the primary creep regime (Andrade law) followed by a power law acceleration up to rupture over up to four decades in time.

Design of a new 11Cr martensitic steel and evaluation of its long-term creep rupture strengths
Journal of Materials Research and Technology, 2022 A new grade of 11 wt% Cr steel was designed in which no nitrogen was added to minimise the driving force of the Z-phase formation and hence to maximise the stability of the fine MX precipitate particles. But, 6 wt% Co was added to completely suppress the

Creep behavior and cavitation evolution of 15CrMoG steel at high temperatures
Advances in Mechanical Engineering, 2019 15CrMoG steel is a type of heat-resistant steel frequently used in boiler and piping systems. Creep properties of the 15CrMoG steel at service temperatures are not much documented due to the difficulties in obtaining long-term creep data.
