Resum
In this research work, the double differentiation mathematical method was used to identify more accurately the criti- cal stress ሺ ߪ ௖ ) and critical strain ሺ ߝ ௖ ) associated with the onset of dynamic recrystallization (DRX), which is based on changes of the strain hardening rate )ߝ߲/ߪ߲ ൌ ߠሺ as a function of the flow stress (Poliak and Jonas method, simplified by Najafizadeh and Jonas). For this purpose, a low carbon advanced ultra-high strength steel (A-UHSS) microalloyed wi...
