Abstract

Titanium alloys such as Ti-6Al-4V are applied in production of structural parts mainly in aircraft and automotive industry, mostly due to favorable relationships between density and mechanical properties as well as good corrosion and crack resistance. Nowadays the most common process of plastic deformation of this material at the industry is hot forging. In search of cost reduction, powder metallurgy method is very promising, because of potential benefits like more precise control of process parameters. In this respect, determining the parameters of thermo-mechanical processing is crucial due to low formability of Ti-6Al-4V alloy. This paper presents the results of the physical modeling of hot forging of cast and P/M Ti-6Al-4V alloy. Both types of the billets were subjected to hot compression tests using the Bähr MDS 830 thermo-mechanical simulator, under various thermal and strain-rate conditions. The microstructures of the samples manufactured by casting and machined from the compacts were observed and compared after deformation. Moreover, the results of the hardness measurements shown the relationships between the conditions of hot deformation and strengthening of the materials. In the result of the investigations, the favorable combinations of thermo-mechanical parameters of Ti-6Al-4V alloy processing were determined. © 2017 TANGER Ltd., Ostrava.
