This increase in strength corresponds well to the calculation of a dislocation strengthening model using dislocation densities measured from TEM observations.
对组织的观察和位错密度的测量表明，该强化作用与位错强化模型的计算结果一致。
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。
It is mainly because that dislocation slides easily within large twin crystal, which leads to the decrease of strength 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。
Hydroxyapatite (ha) whisker has lower dislocation density and higher tensile strength, therefore it could be used as toughening material in bioceramic.
羟基磷灰石(HA)晶须具有较低的位错密度，较高的抗拉性能，可用作生物陶瓷的增韧材料。
It is considered that special structure of the dislocation and damage accumulation induced by rolled were main factors to make the fatigue strength of the welded joint reduced after rolled prestrain.
分析认为，辊压后材料中位错的特殊结构和材料内部所形成的损伤累积是疲劳性能下降的主要原因。
