The yield strength, yield ratio increase with the increase of annealing temperature, due to the impact of non-martensite and the decrease of movable dislocation density.
受非马氏体组织的影响及可动位错密度降低的作用,屈服强度、屈强比随退火温度升高而升高。
2
It is mainly because that dislocation slides easily within large twin crystal, which leads to the decrease ofstrength and the increase in plasticity.
主要是位错在大孪晶中易于移动,从而造成强度下降,塑性提高。

This increase in strength corresponds well to the calculation of a dislocation strengthening model using dislocation densities measured from TEM observations.
