Misorientation Distribution Function edit page

TODO: Please help to extend this section

Let us consider the uncorrelated missorientation ODF corresponding to our model ODF.

mtexdata titanium

odf = calcDensity(ebsd.orientations)
ebsd = EBSD
 
 Phase  Orientations           Mineral         Color  Symmetry  Crystal reference frame
     0   8100 (100%)  Titanium (Alpha)  LightSkyBlue       622       X||a, Y||b*, Z||c*
 
 Properties: ci, grainid, iq, sem_signal, x, y
 Scan unit : um
 
 
odf = ODF (Titanium (Alpha) → xyz)
 
  Harmonic portion:
    degree: 25
    weight: 1
% the uncorrelated
mdf = calcMDF(odf)
mdf = MDF (Titanium (Alpha) → Titanium (Alpha))
  antipodal:         true
 
  Harmonic portion:
    degree: 20
    weight: 1

Axis / Angle Distribution

Then we can plot the distribution of the rotation axes of this missorientation ODF

plotAxisDistribution(mdf)

and the distribution of the missorientation angles and compare them to a uniform ODF

close all
plotAngleDistribution(mdf)
hold all
plotAngleDistribution(ebsd.CS,ebsd.CS)
hold off
