Abstract:

Forged products made of copper-chromium alloys are considered in the paper. Analysis of possibilities of manufacturing of these products is the main objective of the work. Two technological variants are considered. The first is composed of casting, hot extrusion, cooling, heating to the temperature between 800-900oC, hot forging, cooling, saturation annealing and ageing. It is proved in earlier publications that this technology allows to obtain required properties of products, but it is expensive. Therefore, in the present paper the proposition of substituting the final heat treatment by additional cold forging is considered. Simulations of the manufacturing process for four different products were performed using finite element software FORGE 3. Results of numerical simulations, including the distribution of hardness in the volume of the forgings, are presented in the paper. Implementation of additional cold forging allowed to obtain the required hardness, comparable to that obtained after heat treatment, for some of the forgings.
