Deformation mechanisms of Mo alloyed FeCoCrNi high entropy alloy: In situ neutron diffraction
Biao Cai,Bin Liu,Saurabh Kabra,Yiqiang Wang,Yiqiang Wang,Kun Yan,Kun Yan,Peter D. Lee,Peter D. Lee,Yong Liu +9 more
TL;DR: In this paper, a FeCoCrNiMo0.23 high entropy alloy was processed by powder metallurgy with two conditions: hot extruded and annealed, and in situ neutron diffraction, together with electron microscopy was used to study the deformation mechanisms and concomitant microstructural evolution for both conditions.

Abnormal TRIP effect on the work hardening behavior of a quenching and partitioning steel at high strain rate
M. Z. Wang,Mingxin Huang +1 more
TL;DR: In this paper, the authors observed an abnormal transformation-induced plasticity (TRIP) effect in a 1500MPa Q&P steel and found that the dislocation density in the martensite matrix is suppressed at 1000 s−−1, resulting in a lower work hardening.

Kinetics of flow and strain-hardening☆
H. Mecking,U.F. Kocks +1 more
TL;DR: In this paper, a phenomenological model is proposed to incorporate the rate of dynamic recovery into the flow kinetics, which has been successful in matching many experimental data quantitatively, and it has been shown that the proportionality between the flow stress and the square root of the dislocation density holds, to a good approximation, over the entire regime; mild deviations arc primarily attributed to differences between the various experimental techniques used.

Kinetics of strain-induced martensitic nucleation
Gregory B. Olson,Morris Cohen +1 more
TL;DR: In this paper, an expression for the volume fraction of martensite vs plastic strain is derived by considering the course of shear-band formation, the probability of shears-band intersections, and probability of an intersection generating a martensitic embryo.

Criterion for the action of applied stress in the martensitic transformation
J.R. Patel,Morris Cohen +1 more
TL;DR: In this article, the martensitic reaction is treated as a strain transformation with shear and dilatational displacements, respectively parallel and normal to the habit plane, and the resulting effect on the temperature is calculated from the mechanical work done on or by the transforming region as the resolved shear, and normal components of the applied stress are carried through the corresponding transformation strains.
