The experimental results showed that the dislocation density increased with the cumulative reduction increased.
结果表明:随着轧制过程的进行,累积变形量的增加,位错密度逐渐提高。
The results showed that the dislocation density was very high in as-melt alloy with a small amount of stacking fault and twin.
分析结果表明,铸态合金中含有少量的层错和孪晶,但位错密度较高。
EM observations indicate that the dislocation density is very low in the ELO reg ion.
透射电子显微镜的观测表明在ELO范围内位错密度很低。
The results show that the dislocation density decreases and the subgrain sizes increase with the increase of deformation temperature and the decrease of the strain rate;
结果表明:随着变形温度的升高和应变速率的减小,位错密度减小,亚晶粒尺寸增大;
