Název v původním jazyce

Short crack growth and fatigue life in austenitic-ferritic duplex stainless steel

Popis výsledku v původním jazyce

The kinetics of short crack growth has been studied in austenitic-ferritic 2205 duplex stainless steel. Smooth cylindrical specimens and specimens with shallow notch were subjected to constant plastic strain amplitude loading. The crack growth was studied in notched specimens. The notch area has been mechanically and electrolytically polished to facilitate the observation of crack initiation and growth. The initiated cracks were observed in SEM. The crack growth was studied using long distance QUESTAR optical microscope equipped with high-resolution camera. In constant plastic strain amplitude loading the micro-cracks were initiated and their growth kinetics has been studied. The characteristic features of the crack growth at different plastic strain amplitudes were recorded. Two approaches to analyse the crack growth rates were adopted. The comparison of the prediction of the fatigue life using the plastic strain dependent crack growth rate was compared with Manson-Coffin law and t...
