Methods of preparation of TiNb based alloys
Original language description
Two methods were used for preparation of TiNb alloy. First method consisted in vacuum electron beam floating zone melting of Ti rod wrapped with Nb wire. Solution heat treatment at 900°C for 1 hour in flowing Ar gas, water quenching and precipitation hardening at different temperatures (200, 400 and 600°C) for 1 hour were performed on the prepared Ti-25Nb (at.%) alloy. Plasma furnace melting was second method to prepare the experimental alloys with nominal composition of Ti-22Nb and Ti-25Nb (at.%) usingTiNb (55/45 wt.%) master alloy and Ti pieces. Heat treatment at 1100°C for 12 hours in flowing Ar gas and water quenching of prepared samples were realised. Metallographic observation, microhardness measurement and microanalysis of prepared alloys wereperformed in as-melted and heat treated conditions. The effect of heat treatment and Nb content on the microstructure and microhardness was found.
