Sažetak
The paper presents an improvement in the process of forging titanium alloys in order to prevent significant unevenness of the structure due to changes in the technological parameters of the existing production in the conditions of LLC “Dnepropetrovsk Steel” affects the resulting structure and mechanical properties of the semi-product, which in turn possible to obtain a satisfactory macro- and microstructure of the pipe billet, which characteristics ensured the defect-free pressing of the front pipes with a size of Ø 78 × 14 mm on a horizontal hydraulic press and subsequent cold rolling of pipes measuring Ø 19, 05 x 1, 6 mm with mechanical properties that meet the requirements of the regulatory documentation ASTM B 338-91a “Standard Specification for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers”.
