项目摘要

Thermodynamic database on Co-base alloys has been constructed based on the experimental determinations and thermodynamic assessments by Calphad (Calculation of Phase Diagrams)approach. Using this database, a new type of Co-base superalloys strengthend by the L1_2 compound of γ' Co_3(Al, W)phase has been designed. The developed wrought Co-base superalloy shows the expected creep strength of 100MPa at 800 oC for 10^5 hours, while the cast Co-base superalloy has been applied to the FSW (Friction Stir Welding)tool for practical use. It is shown that the Co-W thin film and Co-based Heusler alloys are attracted for magnetic recording media and spin electronics, respectively. Furthermore, the optimum conditions for compositions and heat treatment to form porous structure on the surface to develop drug eluting stent have been obtained by microstructural control of γ (fcc)/β (B2)lamellar structure of Co-Al-based alloys.
采用相图计算(calphhad)方法,根据实验结果和热力学评价,建立了钴基合金的热力学数据库。利用该数据库,设计了一种以γ′Co_3(Al, W)相的l_2化合物为强化材料的新型钴基高温合金。所研制的锻造Co-base高温合金在800℃、10^5 h下的蠕变强度可达100MPa,而铸态Co-base高温合金已在搅拌摩擦焊(FSW)工具上得到实际应用。结果表明,Co-W薄膜和co基Heusler合金分别适合作为磁记录介质和自旋电子学材料。此外,通过对co - al基合金γ (fcc)/β (B2)片层结构的微观组织控制,获得了制备药物洗脱支架所需的最佳成分和热处理条件。
