Microstructure and Texture of Hydrostatic Extrusion Deformed Ni Single Crystals and Polycrystal
Abstract
The differences in the microstructure and texture of two Ni single crystals, with different initial orientations ( <100> and <110> ), and of polycrystalline nickel, before and after severe plastic deformation (SPD) produced by hydrostatic extrusion (HE), have been investigated. The crystals were deformed by a two-step HE process with a total deformation value of ε=1.2. The global texture, mechanical properties, and microstructure were examined after the deformation. In every investigated sample, the presence of <111> fibre texture was noted, while the starting orientation of a <100> Ni single crystal was preserved in 50% of the volume. The results obtained were compared with the relevant literature data.
