Abstract

In this invistigation fracture mechanics approaches have been employed to study the fracture behaviour of austenitic steel at normal and elevated temperatures. Test conditions range from ambient to elevated temperature, monotonic to cyclic loading, and creep strain. Work carried out has been classified into two stages. Firstly, creep, creep -fatigue and fatigue fracture on noteched and unnotched specimens at room temperature. Secondly, creep, creep - fatigue and fatigue at high temperature ranging at about 0.06 0.12, 0.18, 0.24, 0.30, 0.36 and 0.42% of metal melting point for nonheat-treated austenitic steel on unnotched specimen. There after, experiments have been conducted for creep , creep-fatigue and fatigue tests at o'ifferent elevated temperatures on specimens having V notch. In these cases, smooth specimens loaded under uniaxial conditions have been employed to elucidate the steady state creep , creep fatigue and fatigue and fracture mechanisms. A critical analysis of data has revealed the Occurence of a kink similar to that observed in the low carbon steel. On the basis of the study, the behaviour of austenitic steel, at high temperature, and the experimental results have been analysed and recommendations for applications are made.
