LOW CYCLE FATIGUE AND CREEPFATIGUE BEHAVIOROF A HIGH TEMPERATURE ALLOY ON SMOOTH ANDNOTCHED SPECIMENS

Abstract

Abstract: A series of low cycle fatigue and creepfatigue tests on smooth specimens and notched specimens were performed with a high temperature alloy used in the manufacture of aeroengine turbine discs. The cyclic stressstrain behavior and fracture characteristics of the notched specimens were emphatically investigated. A comparison of fatigue behavior between smooth and notched specimens was done and lifetime of notched specimens was evaluated. At the same temperature, the fatiguecreep lives of the smooth specimens are far greater than that of the notched specimens.

Key words: low cycle fatigue, creepfatigue, stress concentration, notch effect
