The temperature-composition phase diagram of the Ni-Cr system was calculated using a first-principles approach based on a statistical-mechanical approximation for the configurational entropy and a tigh-binding method for electronic structure calculations. A self-consistent tight-binding Hamiltonian with ...

图9 长条状μ相的TEM分析结果Fig.9 TEM analysis results of long strip μ phase 长条状μ相的X射线能谱法(EDX)线扫描结果见图10。从图10可以看出，Haynes 282合金中长条状μ相富含Mo、Cr和Co元素，且在长条状μ相两侧出现Mo、Cr和Co元素的贫化现象。根据EDX线扫描结果，可以将长条状μ相分为A、B和C 3...
After annealing at 940 and 1100°C, the phase equilibrium was reached in the Ni-rich part of the ternary in agreement with the published bulk phase diagram. Annealing the materials library at 940°C is not sufficient to achieve the equilibrium state in the Re-rich part of the system, ...
经酸腐蚀试验后,Cr3+和 Mo6+的含量明显增加,Mo4+出现,表明 Cr 和 Mo 形成的稳定 金属氧化物和致密钝化膜是涂层优异耐酸腐蚀性能的主要原因。 此外,与在 CoCrFeNi 四元高熵合金中非金属元素添加的影响不同,Yang[59]和 Yu[60]等人研究了 N 和 Si 掺杂...
