Abstract
⺠Martensitic lath structure rearranges into cells/subgrains causing cyclic softening. ⺠Cyclic softening process is highly sensitive to temperature and application of hold. ⺠Lower CSR of weld joint compared to base metal due to soft zone in the HAZ. ⺠Failure location of WJ depends upon temperature and direction of hold application. ⺠Enhanced cracking due to strain localization and creep cavity formation in HAZ. ⺠Compression dwell sensitivity due to the deleterious effect of the surface oxides.
