EBSD.KAM edit page

intragranular average misorientation angle per orientation

Syntax

plot(ebsd,ebsd.KAM ./ degree)
% ignore misorientation angles > threshold
kam = KAM(ebsd,'threshold',10*degree);
plot(ebsd,kam./degree)
% ignore grain boundary misorientations
[grains, ebsd] = calcGrains(ebsd)
plot(ebsd, ebsd.KAM./degree)
% consider also second order neighbors
kam = KAM(ebsd,'order',2);
plot(ebsd,kam./degree)
% consider all neighbors within a physical distance instead of order
kam = KAM(ebsd,'radius',3*dxy);
% weight neighbors by a kernel function of their physical distance
kam = KAM(ebsd,'order',3,'weights',@(d) exp(-(d/dxy).^2));

Input

ebsd EBSD

Options

order consider neighbors up to graph-distance n (default 1)
radius consider neighbors up to physical distance r, instead of order
threshold ignore misorientation angles larger than threshold
max take not the mean but the maximum misorientation angle
weights function handle psi(distance) weighting each neighbor by its physical distance (default: uniform weight 1)
