Effect of Machining Velocity on the Crystallographic Textures in a Diamond Turned Aluminium Single Crystal

Received20 Mar 1999

Abstract

The orientation changes in the crystallographic textures of a diamond turned aluminium single crystal have been investigated. The X-ray pole figures were collected at various locations on the surfaces turned at high speed. In the central part of the turned surfaces, the pole figures revealed the presence of a thin deformed layer. Four sets of slip systems were found to operate to a very similar extent. However, as the distance from the centre increased, the operation of these four sets of slip systems varied and the textural changes were found to be increasingly affected by the cutting velocity. In a separate grooving experiment, electron back-scatter diffraction (EBSD) patterns were collected at various locations along the bottom part of the groove. These patterns revealed a lattice rotation on the machined surface which was induced by shearing along the cutting direction.
