About application of three dimensional analyses of fracture surfaces in fracture study on nanostructured titanium

► The research on fracture behavior of nanoTi is limited. ► NanoTi is obtained via equal channel angular pressing. ► Standard mechanical fracture tests are carried out. ► 3D analysis of fracture surfaces in nanoTi is performed. ► 3D analysis of fracture surfaces is of great help in experimental fracture studies of nanoTi.
