Low-cycle fatigue of austenitic welds. Analyses of collected data

Technical Report:

Abstract

The austenitic stainless steels are used for the main vessel and other main components of LMFBRs. Various grades were specified in the past: 316 stainless steel for plants in the UK, 304 stainless steel for SNR 300, 316L steel modified for Superphenix. The weld metals used in relation to these parent materials were: (i) several grades of Mo containing weld metals as 17Cr8Ni2Mo (UK), 19Cr12Ni2Mo (France) and 16Cr8Ni2Mo (France and USA). (ii) CrNi weld metals (USA on 308 and Germany on 18Cr11Ni). In a preliminary part of this work, low-cycle fatigue (LCF) data were collected for a number of austenitic weld metals, over range of temperature (20 to 625 deg C), orientation and composition. The second part of this programme involves statistical analyses of the database, to determine the influence of a range of factors on fatigue life and on cyclic behaviour. Both fatigue stress strain and fatigue life results of welds have been compared to weld metal and base metal data. In each particular situation (strain, stress control cycle, stress, strain range, weld thickness) apparent discrepancies have been discussed. Mean curves have been established. Statistical analyses of available data on weld metals, with and without molybdenum addition, used respectively  More>>

Statistical analyses of available data on weld metals, with and without molybdenum addition, used respectively for welding of 316L (N) and 304 stainless steels, have been performed using three types of equations: Basquin-Manson-Coffin, Langer and multiple regression. The analysis of particular tests and comparison of the various mean curves have provided information about: comparison of regression analysis, orientation effects, temperature effect, composition effect, comparison with parent material, cyclic stress-strain behaviour.
