Hi All,
In the context of tensile testing of low-carbon (ferrite/pearlite) steel, are there any studies about the effects of composition (specifically manganese content) on the work hardening rate (slope) or strain hardening exponent (power law exponent) of the plastic portion of the stress-strain curve?
- Does manganese raise the work hardening rate?
- Could the effect be due the influence of manganese on solid solution strengthening, grain refinement or an increase in pearlite?
Thank you!

Mn have no significant affect on the work hardening in low carbon steel. Manganese is a major alloying element, has complex interactions with Carbon and is used to control inclusions. Manganese is beneficial to surface quality in all carbon ranges with the exception of rimmed Steels and is particularly beneficial in high-sulfur steels.
Hi, I recently investigate the effects of severe partitioning of Mn between the phases during different processing routes of low carbon dual phase steel which has significant influences in work hardening rate, hope it would be helpful.
Hi Maryam,
Thank you for sharing your paper! It is quite interesting, but not exactly what I'm looking for. It appears you used a single alloy with 1.11 wt% manganese and showed how the partitioning affected work hardening rate. I'm interested in seeing data about the effects variation in bulk manganese content (in the range of 0.25 to 1.5 wt%) in slow-cooled ferrite/pearlite steels. Thanks again!
Nathan
