六方金属在疲劳过程中的位错组态演化──兼论位错理论和协同论在材料强度学中的应用

THE DISLOCATION CON0IGURATION EVOLUTION DURING FATIGUE PROCESS IN HCP METALS──WITH A DISCUSSION ON THE APPLICATION OF DISLOCATION THEORY AND SYNERGETICS IN MATERIALS SCIENCE

简述了位错理论发展及在中国传播的历史、位错理论的应用领域、金属中常见的位错组态；介绍了协同论在位错研究中的应用，并据此分析讨论了在钛、锆等六方金属中所获得的某些实验结果。

This paper gives a brief overview of the history of the progress of dislocation theory and its studies in China, the application of dislocation theory,and the typical dislocation configurations in metals. The synergetics concept applied to dislocation research, and some of recent results obtained in HCP titanium and zirconium are also introduced.
