Tensile behaviour of high temperature forged Ti-6Al-4V during in-situ heat treatments

Abstract Tensile behaviour of the α + β Ti-6Al-4V titanium alloy is investigated while quenching. A new in-situ thermal and mechanical treatments facility is developed. Different time-temperature and time-mechanical strain histories are coupled to investigate the uniaxial tensile properties and strength of this alloy during quenching. The microstructural evolutions are reported and their influences on the mechanical behaviour are addressed.
