A load-controlled cyclic test inthe low-cycle fatigue regime was utilized to study mechanical response and microstructural changes in the alloyafter reverse phase transformation heat treatment. Deformation-induced FCC → HCP phase transformation wasfollowed using in situ synchrotron X-ray diffraction combined with ex situ electron backscatter diffraction andscanning electron microscopy. Scanning transmission electron microscopy provided experimental evidence of thepresence of precipitates in the solution annealed sample. It was found, that a stepwise increase in plasticdeformation is attributed to nucleation and growth of different martensitic crystallographic variants. These insightsinto plasticity and microstructural changes suggest that the reverse phase transformation heat treatment isan effective approach for improving the fatigue resistance of low stacking fault energy alloys, that are susceptibleto deformation-induced martensitic transformation.}, cin = {FS-NL}, ddc = {530}, cid = {I:(DE-H253)FS-NL-20120731}, pnm = {632 - Materials – Quantum, Complex and Functional Materials (POF4-632)}, pid = {G:(DE-HGF)POF4-632}, experiment = {EXP:(DE-H253)Nanolab-04-20150101 / EXP:(DE-H253)P-P07-20150101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:001362355200001}, doi = {10.1016/j.msea.2024.147493}, url = {https://bib-pubdb1.desy.de/record/619758}, }
