Conclusions

(1)
According to the features of dynamic recovery for body-centered cubic metals, the mathematical expression of the stress-strain Curve describing its hot defermation is\(\sigma (\varepsilon ) = \sigma _s \cdot th^{1/2} \left( {\sqrt {\frac{{\mu bMZ}}{{\upsilon _0 }} \cdot \frac{\varepsilon }{\varepsilon }} } \right)\).

The stress-strain expression derived and the experimental result are very consistent.
