New Electroslag Technology for Producing Manganese-Containing Titanium Alloys

Abstract:

Using the magnetically controlled electroslag melting method, ingots of the manganese-containing titanium alloy OT4 (Ti–4Al–1.5Mn) were produced from the initial charge components. The as-cast metal was subjected to hot rolling followed by annealing. The chemical analysis showed that the manganese and aluminum content in the ingots matched their levels in the initial charge. No reduction in their concentration in the alloy was detected after single or double remelting. They are evenly distributed along the height and radius of the ingot. The gas content does not exceed the limits established for alloys of this type. Macro-and microstructural analysis of the as-cast and deformed metal did not reveal any pores, cracks, non-metallic inclusions. The mechanical properties of the deformed metal meet the standard requirements for premium-quality OT4 alloy bars. Thus, the conducted research demonstrated the feasibility of producing Ti-alloys with a given content of manganese using magnetically controlled electroslag melting method.
