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) |
