Which consequence results when workpiece temperature is too low during isothermal forging of titanium?

A)Grain boundary pinning occurs rapidly
B)Recrystallization kinetics limit deformation
C)Oxidation rate substantially accelerates
D)Eutectic phase formation is enabled

💡 Explanation

Insufficient workpiece temperature during isothermal forging hinders the diffusion-controlled creep, because thermally activated recrystallization kinetics become rate-limiting, halting further deformation rather than allowing creep. Therefore, the material's ductility decreases. Oxidation is avoided through shielding, not temperature.
