摘要：
The introduction of prismatic dislocation loops in the interface between a misfitting spherical particle and its semi-infinite matrix has been theoretically investigated. The equilibrium position of one isolated loop has been first determined from an energy variation calculation and a shifting effect on the dislocation position relative to the particle equatorial plane has been identified due to the matrix free-surface. The case of two dislocation loops lying in the particle-matrix interface has been then discussed. (C) 2020 Elsevier Ltd. All rights reserved.
