Work hardening in Fe–Mn binary alloys

The work hardening rate (WHR) of Fe–Mn binary alloys with Mn content in the range 0.42–1.21 (wt.%) has been investigated in tensile tests at different temperatures. The results show that the WHR depends on temperature and Mn content. We have concluded that the experimental results are in agreement with the model that the change of dislocation density with strain is considered to be a result of the storage and annihilation of dislocations.
