Improvement of mechanical properties for some Ti-Mo-Fe alloys by heat treatment

Abstract

The mechanical properties of Ti-Mo-Fe alloys were enhanced by applying a specific heat treatment. Five alloy samples with various Fe concentrations (1%, 2%, 3%, 4%, and 5%), were subjected to optical (OM) and scanning electron microscopy - energy-dispersive spectroscopy (SEM-EDS) analysis. The heat treatment involved quenching at 750˚C for 60 minutes followed by water cooling, and a subsequent ageing heat treatment at 550˚C with two different holding times, 240 minutes followed by water cooling, and 360 minutes followed by water cooling. The results of the study showed improved mechanical properties.
