The unusual character of microstructure evolution during “abc” deformation of commercial-purity titanium

چکیده
Microstructure evolution during “abc” deformation of commercial-purity titanium was investigated. Continuous dynamic recrystallization (CDRX) played a dominant role in the microstructural changes, although mechanical twinning also contributed to some extent. It found that CDRX developed preferentially at original grain boundaries, thus resulting necklace-type microstructure. This effect attributed comparatively-high local stresses these areas, which promoted pyramidalslip and enhanced deformation-induced boundaries. established changes strain path resulted noticeable re-organization pre-existing dislocation structure due Bauschinger Effect essential material softening. phenomenon retarded boundaries tended lead stagnation microstructure refinement.

Microstructure Evolution during Tensile Deformation of a Nanostructured Bainitic Steel
In situ neutron diffraction experiment was used during tensile testing at room temperature to examine the changes on the percentage and texture of both ferrite and austenite in a nanocrystalline bainitic steels transformed at two different temperatures 200°C and 300oC for different times to achieve the same phase percentages. Both samples showed an inadequate capability of austenite to transfor...
متن کامل3D reconstruction of microstructure in a commercial purity aluminum
The topic of reconstruction of polycrystalline microstructures is briefly reviewed. An example is given of using orientation maps to reconstruct digital microstructures with a representation of a polycrystal structure that includes crystallographic orientation information. The method uses packing of ellipsoids to approximate the grain structure, coupled with Voronoi tessellation. For the exampl...
