摘要

Abstract

Small addition of oxygen is currently used to improve the mechanical properties of titanium. It has been thought

until now

that oxygen fully dissolves in the titanium matrix

thus leading to a solid solution. However

we show here

with transmission electronic microscopy and X-ray diffraction

that oxygen can also form ordered precipitates with a Ti

O-type structure

even for a concentration as low as 0.15 wt% O. The ordered precipitates found in a series of pure binary Ti–O alloys are also visible in commercially pure titanium

including grades 2 and 4

two compositions widely used for technological applications.
