Abstract:

Titanium alloys are one of the most cost-intensive materials to machine with conventional machining methods. It is connected with its mechanical properties, as well as low thermal conductivity and also high material losses during machining. An alternative to conventional titanium machining is electro-discharge machining, which enables to machine all the materials, which are conductors or semi-conductors regardless of its chemical composition and mechanical properties. Heat treatment of Ti10V2Fe3Al alloy allows to obtain different morphology and volume fraction of the α phase, which enables reaching a similar level of strength as in high-strength construction steels. The volume fraction of the α and β phases in titanium alloy can be controlled by the chemical composition of the titanium alloy and the applied heat treatment. In this paper, the results of electro discharge machining of Ti10V2Fe3Al alloy with different (α + β) structures were presented. The main goal of the research was to determine the influence of different titanium alloy Ti10V2Fe3Al structure (with α + β phase) on surface integrity after electro discharge machining process.
