摘要: Abstract The results of 15 years systematic experimental and theoretical study are given the basic concepts fundamental phenomena taking place during interaction accelerated ions with solid crystals—a long-range effect—are developed. effect consists a change in defect structure and/or structural-phased state ion-affected zone ion-implanted target, which is located directly beyond implanted where stopped. thickness microstructure modified ion implantation varies from several up to tens micrometers more. features structures formed adduced. accompanied by development considerable mechanical stresses zone, appear be static, dynamic stresses. These sufficient for initiation mechanisms accumulation dislocations target. metallic materials analyzed.
