Titel
Texture inhomogeneity in titanium deformed by ECAP
Abstract
Titanium of commercial purity was deformed by equal channel angular pressing (ECAP) with back-pressure at 380 degrees C using 4 passes of route B-C. Billets of 120 min length were pressed at 0.4 min s(-1) through square channels (14 mm x 14 mm) intersecting sharply at an angle of 90 degrees. The global texture measurements of the starting and ECAP processed material were done by neutron diffraction. To investigate the texture inhomogencity after ECAP the local texture was measured with high-energy synchrotron radiation at different positions in the cross-section of the billet. The texture gradient with regard to intensity and orientation of the dominant texture component is characterized and discussed.
