The influence of changes in the value of the heatinput on the structural features of ZHS6U alloy products formed by the wire-feed electron-beam additive technolog
Investigated the influence of the parameters of the wire electron-beam additive process on the structure of the final product. It is shown that it is possible to obtain defect-free products with directional structure by this method. The features of the structure of the material formed by additive method and its differences from the original cast material were investigated. The influence of the heat input on the structural stability and the primary dendrite arm spacing (λ1) has been established. It is shown that the dynamic change in the electron beam current contributes to the deceleration of the increase in the value of λ1. The obtained values of λ1 testify to reaching the values of temperature gradients necessary for the realization of directional crystallization.
