摘要：

High mobility crowdions move in the lattice with subsonic and even supersonic velocity with the mass and energy transfer. This work studies the interaction between supersonic 1- and 2-crowdions with point defects in the tungsten crystal lattice. Molecular dynamics simulation shows that the presence of point defects in the row nearest to the crowdion motion path, strongly affects the crowdion dynamics. The mass and energy transfer of supersonic 2-crowdion is found to be more effective than that of the 1-crowdion.
