“…The obtained value of residual weighted profile (Rwp) is in between 7.4 % and 9.1 % as well as Goodness of fit (GoF) is lying between 0.9 and 1.6. Ti-25V-15Cr-0.2Si [56] and Ti-30Zr-5Al-3V [57]. Tables 2 and 3 are the summary of the Rietveld analyses, indicating values of lattice parameter, crystallite size and microstrain of the several α and β planes, respectively.…”

“…The logarithm of work hardening rate, ln(dσ/dε), versus logarithm of true stress, lnσ, is plotted for all the samples in Fig. 7a [56] and [57] for Ti-25V-15Cr-0.2Si and Ti-30Zr-5Al-3V alloys, respectively. As Ti-55521 alloy contains 1 % more Cr, which has a much smaller atomic radius compared to elemental Ti, this results in an expected slightly smaller bcc lattice parameter than that for Ti-55511 alloy.…”

The effect of cooling rates on the microstructure and mechanical properties of thermo-mechanically processed Ti-Al-Mo-V-Cr-Fe alloys AbstractTwo near-β titanium alloys, Ti-5Al-5Mo-5V-1Cr-1Fe and a modified one containing 2 wt% Cr (Ti-5Al-5Mo-5V-2Cr-1Fe) were produced from Ti hydride precursor powders via the cost-effective blended elemental powder metallurgy technique. The effects of two cooling rates (10 K s−1 and 1 K s−1) during thermo-mechanical processing on the microstructure and mechanical properties were investigated using X-ray diffraction and scanning electron microscopy. X-ray line profile analysis revealed that dislocation densities and microstrain in β-Ti phase are higher than in α-Ti phase for all cases. In both alloys, slower cooling results in an increase in α volume fraction and promotes morphology of continuous grain boundary α phase. A lower total elongation is obtained in both alloys under slower cooling which could be accounted for by the continuous morphology of α phase. Overall, Ti-5Al-5Mo-5V-1Cr-1Fe displays higher ultimate tensile strength and total elongation compared to Ti-5Al-5Mo-5V-2Cr-1Fe, regardless of the cooling rate.

“…They were also supposed to find applications in aerospace industry as they can combine both the advantage of titanium (low density) and zirconium (corrosion resistance) to fabricate AO-resistant alloy with excellent specific strength. Recently, Zr-Ti based alloy with relatively high strength, which can be compared to those of bulk metallic glass, while keep good ductility was developed [13][14][15]. Meanwhile, as their excellent AO-resistance, zirconium dioxide and titanium dioxide have been widely used as oxygen-resistance coatings [16].…”
