摘要：

Laboratory thermal-mechanical processing was used to produce Alloy 600 material with varying microstructures. The materials were fabricated into single U-band specimens and tested in 343 C (650 F) ammonia-hydrazine treated water for over 18,000 hours. Specimens exhibiting significant intergranular carbide precipitation were generally much more resistant to cracking than those that displayed less intergranular carbides. The results of microanalyses of cracked and uncracked specimens are presented, and the influence of various microstructural features are given.
