摘要
介绍了粉末冶金法生产的多晶态铍的性能、生产工艺。综述了多晶态铍室温断裂行为的研究状况,包括铍的室温断裂特征,以及诸如铍粉粒度和形态、粉末压制过程、表面残余应力,机械加工损伤、多种杂质(BeO,Fe,Al,Cr,Ag,Si,C等)对铍室温断裂性能的影响。预测了未来关于铍在工程领域可能开展的基础性研究。
Performances of polycrystalline beryllium and its technological process of production are introduced. Its fracture behaviors at room temperature is also reviewed, which included： fracture characteristics; influence factors of fracture performances such as size and shape of beryllium powders, process of powdered metal compacting, surface residual stress, machine-damage, and impurities （BeO, Fe, A1, Cr, Ag, Si, C, etc） embedded in grains. By authors＇ opinion the basic researches of beryllium in engineering may be carried out in future is forecasted at the end of the paper.
