Fázové transformace a mikrostrukturní změny ve slitině TIMET LCB / Fázové transformace a mikrostrukturní změny ve slitině TIMET LCB

Šmilauerová, Jana January 2012 (has links)
In the present work, phase transformations in TIMETAL LCB tita- nium alloy and their influence on mechanical properties were studied. Different initial conditions were prepared by solution treating above β-transus immedi- ately followed by heat treatment in α/β temperature regime. These resulted in different grain boundary α thicknesses and contiguities at a fixed α vol- ume fraction. The subsequent ageing response of this material was studied by low temperature ageing at 400 ◦ C, 450 ◦ C and 500 ◦ C. Phase transformations were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and resistivity measurements. Mechan- ical properties were investigated using microhardness measurements and tensile tests. It has been proved that metastable ω phase is formed during annealing at 400 ◦ C and 450 ◦ C. ω particles further transform to very fine precipitates of α phase when exposed to annealing for longer time periods. These fine precip- itates significantly contribute to increase of microhardness and achieving high value of yield stress.
