Investigation of the Diffusion Processes at the Interface of the Cu/Ti Metal Composite

Abstract:

In this study the impact of heat treatment on the structure of Ti/Cu laminated metal composite was investigated. The composite was fabricated via explosion welding and was subsequently hot rolled. Optical tests, SEM microscopy and microhardness tests were utilized to identify the phase composition and the structure of diffusion zones formed at the interface between metals during heat treatment. Heat treatment of the composite for less than 1 hour results in the formation of two interlayers with the Ti_α+Ti₂Cu and TiCu phase composition respectively. The increase in the heat treatment duration up to 10 hours results in the formation of two additional interlayers with the Ti₃Cu₄ and Cu_α + βTiCu₄ phase composition.
