Abstract : The report includes: (1) an analysis of notch toughness of AISI 304 and 316 stainless steel submerged arc weldments, (2) information on fatigue crack growth in austenitic stainless steel welds, (3) an analysis of residual element effects on radiation strengthening in iron alloys, pressure vessel steels and welds, (4) electron microscopy observations of defect aggregates in irradiated iron and 0.3 copper-iron alloy, and (5) the development of a damage function for 550F (288C) embrittlement of A302-B steel.
