The Influence of Molybdenum Equivalent on the Anisotropy of Thermal Expansion of Titanium Martensite Lattice

The structure of the martensite formed by quenching in titanium alloys, as well as the connection between the rhombic lattice α - martensite and anisotropy of thermal expansion was investigated. Τhe methods of the X-ray and thermal XRD phase analyzes have been used to study the relationship between martensite crystal lattice, the coefficient of thermal expansion (CTE) and molybdenum and aluminum equivalent.     Keywords: titanium alloys, martensite, CTE, XRD-analysi
