Fatigue-crack-propagation thresholds in a nickel-base superalloy at high frequencies and temperatures
Fatigue-crack-propagation (FCP) tests were conducted on the powder metallurgy nickel-based super-alloy KM4 at temperatures of 20 degrees Celsius, 550 degrees Celsius and 650 degrees Celsius. The roughness of the fracture surface was found to increase as the load ratio was increased for both microstr...

Summary: | Fatigue-crack-propagation (FCP) tests were conducted on the powder metallurgy nickel-based super-alloy KM4 at temperatures of 20 degrees Celsius, 550 degrees Celsius and 650 degrees Celsius. The roughness of the fracture surface was found to increase as the load ratio was increased for both microstructures. |
