Final stretch zone width determination for MP35N multiphase alloy
Апстракт
This paper presents an experimental elastic-plastic fracture behaviour analysis in order to evaluate a resistance of the aged and unaged MP35N alloy to stable and unstable crack growth. MP35N fracture behaviour has been investi-gated under static loading conditions, so J-R curve and JIC testing results are presented. Another important task was to obtain and investigate SEM microphotograph of fracture surface for various specimens and to analyse the micro-structure in the stretch zone. The results indicate that around the crack tip at the stage of crack initiation mixed loading conditions are predominant. An attempt has been made to determine the final stretch zone width as a fracture parameter for the MP35N alloy. It is possible to correlate results for average SZW with obtained JIC values, and suffi-ciently good agreement between them is shown.
