The Structural Changes in Surface Layer of Matrix Aluminum Alloys 1201 and 6111 in Area of Pulsed Beam of Relativistic Electrons Influence in Pre-Melting Regime
Abstract
In this work the features of the relativistic pulsed beam of electrons influence on the processes of structure formation in surface layer of industrial aluminum alloys 1201 and 6111 in pre-melting regime are investigated. It is shown, that in selected pre-melting regime - till the macroscopic surface melting in beam influence zone - the local melting and the subsequent crystallization of separate volumes of surface layer microstructure of alloys occurs. It is supposed, that the appearance of similar areas of microstructure of aluminum alloys 1201 and 6111 can be associated as with the nonequilibrium eutectics melting as with the melting of the segregations of alloying elements.
