TLDR
The flow stress of steels with a structure of divorced pearlite is lower than that of steel with lamellar pearlite, the difference increasing with the carbon content of the steel, i.e., with increasing amounts of pearlite in the structure as discussed by the authors.Abstract:
1.
The carbon content and the shape of cementite in the steel (lamellar or granular) have a substantial effect on the flow stress during cold plastic deformation. The formulas obtained in this work make it possible to determine this value quantitatively.

Strain hardening of sintered iron during cold plastic deformation
TL;DR: In this article, the authors found that increasing the particle size of the original powder to >63 μm leads to a smaller increase of density during cold plastic deformation, while increasing particle size increases the strength.

TL;DR: The applicability of the Ludwik, Hollomon, Swift and Voce equations in describing the stress curves of metals was investigated in this paper, where the authors found that the uniform strain values depend on the equation used.
