文摘

High temperature deformation behavior of a duplex low density steel is explored. The progressive sub-boundaries formation and its positive effect on the materials' ductility Deviation of annealing twins from ideal Ʃ3-coincidence due to the substructure development Continuous transformation of subgrains into the recrystallized grain at higher strain rates Continuous recrystallization favours the grain boundary sliding and deteriorates the ductility.
