dislocation density
The dislocation density can be determined as follows.
There is then a reduction of the dislocation density.
The emergent dislocation density was determined by counting the observed dots.
The lattice strain increases with the increase in the dislocation density.
The dislocation density in the martensite contributes to the improvement of tensile strength.
Working without causing a change in dislocation density and is called recovery.
The initial dislocation density considered in the simulations is close to the one measured experimentally.
This in fact invol ves the nucleation of new grains of low dislocation density.
Stress values from dislocation density measurements vary inversely with metamorphic intensity.
We then present a spectral method devoted to the solution of the dislocation density transport equation.
The average dislocation density p of the thinnest wall portion is measured by the following method.
The dislocation recovery rate is higher with increased temperature and increased dislocation density.
The dislocation density decrease itself is effective for SSC resistance enhancement.
The model considers crystal plasticity and deals separately with mobile dislocation density and dislocation velocity.
In this case, the dislocation density becomes decreased.

Thus, the steel can be reinforced by precipitation strengthening, independent of the dislocation density.
Furthermore, the dislocation density is not sufficiently reduced.
Accordingly, it is preferable that the dislocation density be low.
For this reason, the dislocation density of the steel having been tempered increases.
While using as an intermediate variable, the dislocation density p such that.
The dislocation density in the steel becomes reduced by carrying out the high-temperature tempering step.
In general, tempering means reducing a dislocation density by a heat treatment.
We also study, in a theoretical and numerical way, a model for the dynamics of dislocation density.
In the high-temperature tempering step, dislocation density in the steel is reduced.
The crystal quality was relatively good, although contained crystallographic twins and moderate dislocation density.
Hereinafter, definition reasons of the average dislocation density are density are described.
The dislocation density was calculated through the evaluation method based on the above-described Williamson-Hall method.
Further, if the tempering temperature is low, dislocation density is not decreased.
Hence, if the dislocation density is lower, the SSC resistance becomes enhanced.
In the high-temperature tempering process, dislocation density in the steel is reduced.
When dislocation density in the steel is high, the SSC resistance decreases.
However, high-temperature tempering decreases dislocation density of the inside of the steel pipe.
Hence, if the dislocation density is higher, the SSC resistance becomes enhanced.
It is thought that the half-value width reflects the dislocation density in the steel.
As a result, crystal has a relatively low dislocation density in the multiple quantum well active layer 14.
However, since bainite and martensite are tempered during the annealing, the dislocation density is reduced.
Therefore, with the increase in martensite percentage, the dislocation density after tempering decreases.
Tables 3 and 4 show the effect of the dislocation density.
Finally, we propose a relationship that models the evolution of dislocation density during a recovery heat treatment.
Combined with the rheological model, we present a relationship between dislocation density and Vickers microhardness.
An ELO step allows a possible further reduction in dislocation density ( by at least a factor of 10 ).
