Transformation Pathway upon Heating of Metastable β Titanium Alloy Ti-15Mo Investigated by Neutron Diffraction

A transformation pathway during thermal treatment of metastable [Formula: see text] Ti-15Mo alloy was investigated by in situ neutron diffraction. The evolution of individual phases [Formula: see text] , [Formula: see text] , and [Formula: see text] was investigated during linear heating with two he...

description A transformation pathway during thermal treatment of metastable [Formula: see text] Ti-15Mo alloy was investigated by in situ neutron diffraction. The evolution of individual phases [Formula: see text] , [Formula: see text] , and [Formula: see text] was investigated during linear heating with two heating rates of 1.9 [Formula: see text] and 5 [Formula: see text] and during aging at 450 [Formula: see text]. The results showed that with a sufficient heating rate (5 [Formula: see text] in this case), the [Formula: see text] phase dissolves before the [Formula: see text] phase forms. On the other hand, for the slower heating rate of 1.9 [Formula: see text] , a small temperature interval of the coexistence of the [Formula: see text] and [Formula: see text] phases was detected. Volume fractions and lattice parameters of all phases were also determined.
