Statistical Modeling of Strain-Hardening Exponent and Grain Size of Nb-Microalloyed Steels Using a Two-Level Factorial Design of Experiment

Effect of microstructure on strain hardening and strength distributions along a Cr–Ni–Mo–V steel welded joint

“…In the past several decades, the strain hardening exponent of various materials has been widely investigated. It is now found that the strain hardening of materials are strongly dependent on the microstructures [5,6], grain size [7,8], temperature [9], and strain rate [10,11].…”

Strain hardening exponent and strain at maximum stress: Steel rebar case

“…In this context, the authors consider that a basic and preliminary look at the subjacent straining mechanism may give convenient insights for future research. Several authors [30,31,44,45,46,47,48,49,50,51] have related hardening behavior to strain mechanisms and microstructures.…”

“…After straining to ε gt , there is a notable increase of the number of grains that align their (101) direction to the Y tensile axis. The hardening exponent value may be expected to decrease due to the grain refinement effect observed at ε z =ε gt [30,47].…”
