摘要: The use of transmission electron microscopy (TEM) to examine the microstructure bonding zone in explosive welding is described. Plates an aluminum copper alloy were heat-treated produce a well defined microstructure. With such plates series claddings with different parameters and conditions made. was then analysed. From changes within as compared material original state conclusions are drawn concerning deformation process thermally activated reactions which take place during welding. findings lead more comprehensive understanding process, including maximum temperature zone, cooling rate, mechanism impact plates. It can be shown that achieved by short time melting followed extremely rapid solidification very thin layer along contact interface. A brief discussion on generalization results include materials high temperature, correlation between properties welds presented.
