Microstructure Evolution and Mechanical Properties of Suction Cast Ti₆₀Fe_40-xCo_x (x = 0, 16, 18, 20, 22, 24) Alloys

Abstract:

The present work is aimed at understanding the microstructure evolution in a series of Ti₆₀Fe_40-xCo_x (x= 0, 16, 18, 20, 22, 24) alloys. The ternary alloys are synthesized by arc melting cum suction casting technique under high purity argon atmosphere to obtain alloy cylinders having 3 mm diameter and aspect ratio of 17:1. Detailed X-ray diffractometry and electron microscopic studies are carried out to identify the phases in the investigated alloys. It has been found that the alloys consist of fine scale eutectic matrix between bcc (b-Ti)_ss and Ti(Fe,Co) phases along with the dendritic phase of Ti(Fe,Co), whereas the dendritic phase of Ti₂(Fe,Co) has also been observed for x = 16 and 20. It is also found that ternary Ti₆₀Fe₂₀Co₂₀ alloy shows good combination of compressive strength (~2507 MPa) and plasticity (~16.3 %) among the investigated alloys.
