Microstructure and work hardening evolution of ultrafine-grained and coarse-grained alloys Ti–Nb–Zr and Mg–Y–Nd under tension
The paper investigates the influence of the ultrafine-grained (UFG) structure of Ti–42Nb–7Zr and Mg–2.9Y–1.3Nd alloys on their substructure and strain behavior induced by quasi-static tension. It is shown that the ultrafine grain (UFG) structure provides changes in stress-strain curves. Structural transformations due to quasi-static tension are described for both ultrafine- and coarse-grained structures of these alloys. The alloys with the coarse-grained structure demonstrate the formation of localized deformation bands with misoriented network substructure. The UFG Ti–42Nb–7Zr alloy structure is characterized by the formation of larger equiaxial grains with a lower dislocation density that indicates to a localized alloy softening before fracture. The fracture of the UFG Mg–2.9Y–1.3Nd alloy demonstrates the cellular-network substructure.
