Summary

A study comparing unloading behavior in three steel grades found that steels hardening via phase transformation or deformation twinning exhibit less microplastic strain during unloading than conventional steels. These findings inform the design of high-strength materials but are unrelated to environmental microplastic pollution or health impacts.

The unloading behavior was compared for three different steel grades: a dual-phase steel, a transformation-induced plasticity steel, and a twinning-induced plasticity steel. Steels that harden by phase transformation or deformation twinning exhibited a smaller component of microplastic strain during unloading and a smaller reduction in the chord modulus compared to the conventional hardening steel. As a result, unloading is closer to pure elastic unloading when the TRIP effect or TWIP effect is active.
