Mechanism and kinetics of carbide dissolution in near alpha Ti-5.6Al-4.8Sn-2Zr-1Mo-0.35Si-0.7Nd titanium alloy

► Carbide dissolution occurs at precipitate/matrix interfaces, forming β-depleted zone. ► Peritectoid reaction is responsible for drastic reduction of carbide volume fraction. ► Slower dissolution rate is accounted by dislocation, vacancy flow, and curvature. ► Lamellar changed to equiaxed α with increasing carbon from β furnace cooling.
