This work produced partially recrystallized microstructures by cold rolling and annealing Inconel 625 sheets to simultaneously achieve excellent strength and ductility. The results showed that the sample achieved excellent ultimate tensile strength (1010 MPa) while retaining good total elongation (68%) when most of its equiaxed grains coexisted with a small number of its non-recrystallized elongated grains. The microstructural heterogeneity is caused by preferential recrystallization at high-strain zones due to non-uniform deformation. And the coexistence of excellent strength and ductility is attributed to the coexistence of non-recrystallized grains at a relatively high internal dislocation density and small-sized strain-free recrystallized grains.

这项工作通过冷轧和退火 Inconel 625 板材产生了部分再结晶的微观结构，同时实现了出色的强度和延展性。结果表明，当大部分等轴晶粒与少量未再结晶伸长晶粒共存时，该样品获得了优异的极限抗拉强度（1010 MPa），同时保持了良好的总伸长率（68%）。微观结构的不均匀性是由不均匀变形导致的高应变区的优先再结晶引起的。并且优异的强度和延展性的共存归因于相对高的内部位错密​​度的未再结晶晶粒和小尺寸的无应变再结晶晶粒的共存。
