- Abstract
Mechanical behavior and mechanisms of fracture of the ultrafine-crystalline (UFC) and the coarse-crystalline (CC) aluminum alloy V95 (Al-6.0 Zn-2.3 Mg-2.0 Cu-0.4 Mn (wt %)) manufactured via using severe plastic deformation, namely, by dynamic equal-channel angular pressing (DCAP), have been studied. It has been demonstrated that the UFC material exhibits improved mechanical properties in comparison with the CC analog. A correlation analysis of fracture surfaces and the determination of the Hurst exponent have made it possible to perform a comparative estimation of the uniformity of the fracture structure and of the fractions of ductile and brittle fractures in the samples with the structure-scale characteristics different in value.
