| 英文摘要 | 利用热膨胀仪结合显微组织观察、硬度表征和精细微观组织结构分析,对3种Cu含量管线钢的连续冷却转变行为进行了研究。结果表明,在不同冷速下,组织均由复杂的混合型针状铁素体组成;随着Cu含量增加,组织的晶粒尺寸更细小,获得完全针状铁素体的冷速范围更宽。高Cu含量管线钢的硬度-冷速曲线中会出现硬度峰值,分析认为高Cu含量管线钢在连续冷却转变过程中会在一定冷速下会发生Cu的析出。; AbstractRare-earth tantalates and niobates (RE3TaO7 and RE3NbO7) have been considered as promising candidate thermal barrier coating (TBC) materials in next generation gas-turbine engines due to their ultra-low thermal conductivity and better thermal stability than yttria-stabilized zirconia (YSZ). However, the low Vickers hardness and toughness are the main shortcomings of RE3TaO7 and RE3NbO7 that limit their applications as TBC materials. To increase the hardness, high entropy (Y1/3Yb1/3Er1/3)3TaO7, (Y1/3Yb1/3Er1/3)3NbO7, and (Sm1/6Eu1/6Y1/6Yb1/6Lu1/6Er1/6)3(Nb1/2Ta1/2)O7 are designed and synthesized in this study. These high entropy ceramics exhibit high Vickers hardness (10.9–12.0 GPa), close thermal expansion coefficients to that of single-principal-component RE3TaO7 and RE3NbO7 (7.9×10?6-10.8×10?6C?1 at room temperature), good phase stability, and good chemical compatibility with thermally grown Al2O3, which make them promising for applications as candidate TBC materials. |
