| Abstract: | The disclination model of high angle grain boundaries proposed before is used to understand the energy-angle relations between cusp misorientations. It is found that the model predicts the correct relationship within experimental error with only one adjustable parameter which resembles the Burgers vector of dislocations at low angles. Experimental data for 100] symmetric tilt boundaries in Cu and Al and for 110] symmetric tilt boundaries in Al are used for illustration. |
