陶瓷超导粉末体冷加工变形机理与织构化条件

DEFORMATION MECHANISMS AND TEXTURED CONDITIONS OF CERAMIC SUPERCONDUCTING POWDER IN COLD WORKING

在颗粒介质力学的概率理论和晶体滑移理论的基础上,提出了粉末体冷加工变形的统计学机制,分析了陶瓷高温超导材料粉末体冷加工的变形特征和织构化条件,结果与实验相符。

Based on probability theory for mechanics of particulate media and on the theory of crystal slip, statistical mechanisms for deformation of powder materials in cold working were proposed. Characteristics of deformation and conditions of texture development of ceramic superconducting powder in cold working were discussed and put forward. The results are in consistence with experiments.
