A silica particle observation (SPO) method was used in order to determine experimentally the boundary energies of Sigma 9 [110] asymmetric tilt boundaries with a misorientation angle of theta = 38.9 degrees in Cu for various inclination angles between phi = 0 degrees and 90 degrees. The SPO method has no drawbacks which are inevitable in boundary grooving and tri-junction methods. The boundary energy takes the maximum value at phi = 0 degrees but the minimum value at phi = 65 degrees. The minimum value is 65% of the maximum value. The inclination angle dependence of the boundary energy was utilized to evaluate quantitatively the possibility of faceting and dissociation for the boundary. According to the evaluation, the faceting into the {112} {552} and {552} {112} boundaries is possible for the {778} {110}, {554} {17, 17, 4} and {221} {221} boundaries. Furthermore, the dissociation into the Sigma 3 {111} {111} and {112} {112} twin boundaries is feasible for the {111} {115}, {447} {001} and {778} {110} boundaries. (c) 2007 Elsevier B.V.
