THE EFFECT OF FE ADDITIONS ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF A Ti-Al-Mn ALLOY
Alloys in the dilute Ti-Al-Mn system, which are considered to be near-a alloys, possess an attractive combination of strength and ductility, with the room temperature properties being intermediate between CP Ti and Ti-6A1-4V. Low levels of Fe are often tolerated in such alloys, but rarely introduced as deliberate alloying additions (with the exception of CP Ti grades), and from a processing perspective, it may indeed be desirable to have higher tolerances for Fe as it is often a common contaminant which must be controlled. In this presentation, the effect of 0.3wt.％Fe on the microstructure and behavior of a Ti-0.75wt.％Al-0.75wt.％Mn is reported. It was found that annealing in the (α+β) phase field can lead to an increase in the ductility of the alloy without having a detrimental effect on the tensile strength.
