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.
