A Study on Dynamic Recrystallization Kinetics Model of 45Cr4NiMoV

摘要

The dynamic recrystallization critical strain of this alloy was investigated by Poliak and other scholars using the hardening rate (θ) method; they thought the critical condition corresponded to the inflection point of the lnθ-ε curve and the minimum value on the -{partial deriv}(lnθ)/{partial deriv}ε-ε curve. A dynamic recrystallization critical strain model of 45Cr4NiMoV was established.
