Parameters Evolution of Orthorhombic Martensite Lattice in VT16 Titanium Alloy During Heating

KnE Engineering / XIX International scientific-technical conference “The Ural school-seminar of metal scientists-young researchers” / Pages 193–198

Abstract

The material of the study was (α + β) -titanium alloy VT16. Samples were quenched from different temperatures and then they were heated in situ on X-ray diffractometer. It has been established that the period “b” of the orthorhombic martensite lattice showed negative values of the coefficient of thermal expansion during heating.


 


 


Keywords: titanium alloys, XRD-analysis, orthorhombic martensite, coefficient of thermal expansion.
