【 摘 要 】
In-situ study of heating in an X-ray diffractometer of Ti-8Mo and Ti-3Al-7Mo alloys samples quenched from different temperatures of α+β and β-fields was carried out. The characteristics of anisotropy thermal expansion of orthorhombic martensite lattice were investigated. It is shown that there is a critical ratio of lattice parameters R = 3a/b close to 1.11, after which either a reverse martensitic transformation occurs, or R of the martensite lattice decreases upon further heating.
