Abstract

Chemical composition studies have been carried out for a large-dimensioned experimental-industrial 1,5 tons ingot from high-alloyed high-strength metastable β-titanium alloy VT47, the ingot having been obtained by threefold vacuum-arc remelting in PSC «VSMPO-AVISMA Corporation». A comparative analysis has been completed for the results of 30 kg laboratory ingots investigation (obtained by VIAM experimental production) and those for the large-dimensioned ingot in order to evaluate the scale factor influence on quality characteristics of VT47 ingots. The possible ways of further metallurgical quality increase have been proposed for large-dimensioned industrial ingots from VT47 alloy.
