Abstract

The Misorientation Distribution Function (MDF) was measured for commercial grade seamless 304 stainless steel tubing. Approximately 4000 boundary misorientations were used in the measurement. The results were compared with a theoretical MDF derived from the Crystallite Orientation Distribution Function (CODF) estimated from 1762 individual orientation measurements, and from x-ray pole-figure measurements, assuming grain orientations to be uncorrelated. It is concluded that the derived MDF can predict some features of the measured MDF but not all because of the presence of orientation correlations between adjacent grains.
