Improvement of the work hardening rate of ultrafine grained steels through second phase particles
TL;DR: In this paper, the work hardening rate of various ultrafine grained steels with different carbon contents was studied, and the increase in the amount of finely dispersed cementite particles leads to an improved workhardening rate, which is sufficiently large to balance the negative effect of grain refinement on ductility.

Recrystallization and superplasticity at 300 C in an aluminum-magnesium alloy
TL;DR: In this article, the authors evaluated the superplastic ductility of an Al-lOMg-0.1Zr alloy at 300 °C and found that the super-plastic response can be enhanced by simultaneously increasing the total rolling strain, the reduction per pass, and the duration of reheating intervals between passes during isothermal rolling.
