EN Purpose: The basic aim of the investigations was to determine the effect of a microadditions of zirconium on the improvement of the plasticity of tin bronze type CuSn6 and its deformability during the production test of hot rolling of flat ingots. Design/methodology/approach: The principle method of testing the deformability of flat ingots at elevated temperature was rest of their hot rolling under industrial conditions. Findings: In result of the investigations it has been found that a microadditions of zirconium in an amount of about 0.03-0.05% ensures an optimal structure and also a higher plasticity and deformability of industrial bronze type CuSn6 in the temperature range of hot rolling. Research limitations/implications: Attempts of hot rolling permitted only in a limited degree to determine the favourable effects of the modifications of the tested bronze with zirconium. In future these effects ought be verified in other processes of hot plastic working. Practical implications: The investigations proved that the applied technology of rolling is an effective way of hot plastic deformation of flat tin bronze ingots modified with zirconium.
