Abstract
The mechanical response and microstructural evolution of cold-rolled lean duplex stainless steel 2101 (LDX 2101) has been investigated along the rolling and transverse directions. Compression tests at \( 10^{ - 3} \,{\text{s}}^{ - 1} \) strain rate and up to a strain of 24 and 40% were conducted in a universal testing machine. A comparison was drawn between the cold-rolled LDX 2101 and previously studied hot-rolled LDX 2101. Microstructural examinations were conducted via Electron Backscatter Diffraction (EBSD). Results show that cold-rolled LDX 2101 has a higher yield stress than hot-rolled LDX 2101. Furthermore, the response of cold-rolled LDX 2101 was found isotropic, due to the similar phase morphology along each direction. Finally, phase transformation was observed to occur within the austenite phase for the two strains tested.
