This article examines questions related to improving the quality of hot-worked bimetallic powder materials. It analyzes the technological factors in the first stage of the process of producing a bimetal – cold pressing of the outer layer. A description is given of a technology that eliminates the need for auxiliary structural elements for the compression mold (shells, connectors, etc.), better protects the preform from oxidation while it is being heated prior to finish forging, and improves the quality of the transition layer and the bimetal as a whole.
