The effect of ageing on microstructure and mechanical properties of powder Ti–5Al–5Mo–5V–1Cr–1Fe alloy

“…3). The presence of similar white titanium carbide particles in β-Ti alloys is reported in the literature [20,32,34]. In another study [35], the effect of carbon content on structural changes in α phase in Ti-5Al-5Mo-5V-3Cr alloy has been discussed but they do not mention the presence of such particles.…”

“…Ti55511 alloy during ageing [11,[17][18][19][20][21], while some others reported only microstructural changes without providing data on the mechanical properties [13,22]. Mechanical properties of cast/wrought Ti-55511 alloy after ageing at different conditions are listed in Table 1; they are dependent on the complete processing schedule.…”

“…The effect of the titanium carbide particles on the mechanical properties is mentioned in [20,32]. It has been shown that the addition of C reinforces the strength and reduces the elongation slightly due to the formation of titanium carbide compound.…”

“…On the other hand, the presence of titanium carbide can enhance the high temperature strength, i.e. creep properties of an alloy [20,32]. Since the melting temperature of titanium carbide particles is 3800 K and they remain stable at high temperature, thus they will render strength at high temperature application.…”
