...Cody Gibson; Robert Stephens; Santosh B. Narasimhachary; David E. Mills; Andrew Rosenberger This paper describes pilot test results from a round-robin conducted in support of the standard ASTM E2760 , Standard Test Method for Creep-Fatigue Crack Growth Testing , on creep-fatigue crack growth...

... properties including creep, low cycle fatigue (LCF), creep-fatigue interaction (CFI), high cycle fatigue (HCF), fracture toughness, and crack growth has been generated covering important candidate materials such as alloy 617M tubes and forgings, 304HCu stainless steel tubes, and alloy 625 castings. Tubes...

... under high stress and high temperature causes the creep deformation, ultimately leading to deformation beyond the permitted limit or interference with other components, or both. Hence, a priori using particular material for a specific application, mechanical testing has to be done to investigate its...

... of creep and fatigue loads during the high-temperature operating conditions, and the synergistic action leads to accelerated failure life. The present study aims to assess the effect of interspersed hold at peak load on the fatigue crack growth rate in SS 316 L(N) at test temperatures of 823 K (550°C), 873...

...Avinash Hariharan; Anand K. Kanjarla Single crystal nickel-based superalloys have high temperature creep resistance due to particle strengthening by high volume fraction of coherent γ ′ precipitates distributed within nickel-based solid solution γ matrix. In the high temperature low stress regime...

...B. Rivolta; F. Tavasci; R. Gerosa; J. Yenus Increasing temperature is one of the key factors for improving the efficiency of steam power plants. Important metallurgical phenomena are activated at such high temperatures and creep resistance becomes a driving criterion for the material selection...
