Transformation Pathway upon Heating of Metastable ? Titanium Alloy Ti-15Mo Investigated by Neutron Diffraction.
Ontology highlight
ABSTRACT: A transformation pathway during thermal treatment of metastable ? Ti-15Mo alloy was investigated by in situ neutron diffraction. The evolution of individual phases ? , ? , and ? was investigated during linear heating with two heating rates of 1.9 ? C / min and 5 ? C / min and during aging at 450 ? C . The results showed that with a sufficient heating rate (5 ? C / min in this case), the ? phase dissolves before the ? phase forms. On the other hand, for the slower heating rate of 1.9 ? C / min , a small temperature interval of the coexistence of the ? and ? phases was detected. Volume fractions and lattice parameters of all phases were also determined.
