The microstructure and room-temperature mechanical properties of directionally solidified heat-treated Nb‑16Si‑23Ti‑4Cr‑2Al‑2Hf‑0/0.3/0.5Sc (at.%) alloys were investigated. All consisted Nb-based solid solution (Nbss), α‑Nb5Si3 γ‑Nb5Si3 with preferred 〈001〉 orientation for the first two phases, Sc was enriched in phase. Sc-added showed a more continuous Nbss matrix which finer Nb5Si3 phase distributed uniformly. volume fraction both decreased by addition. alloying reduced Young's modulus...
Abstract In order to achieve the dual carbon goal, a prediction method of industrial emissions based on CNN–LSTM was studied. The extended Kaya identity is used measure emissions, and LMDI decomposition determine influencing factors. model inputs historical emission data, extracts spatial features through CNN, then makes time series by LSTM, finally outputs results. Experiments show that this can effectively predict in different scenarios provide support for goal double carbon.
High-throughput methods were developed to prepare multicomponent NbSi based (NbxCryTizSi1-x-y-zAl0.5) alloy film combinatorial libraries (x = 0 → 0.95, y [0.95-x], z [0.95-x-y]) with composition gradients. Oxidation behavior of the as-deposited was investigated in dry air at 1250 °C. The results show that is consisted a mixture amorphous and crystalline phases. Crystallized composed Cr2Nb, Nb5Si3 Nbss phases after annealing. oxidation °C for different times exhibits three regions distinct...
In this work, pure Nb, Nb5Si3 and Laves Cr2Nb compound powders were used as raw materials to prepare Nb-Si-Cr ternary alloys by spark plasma sintering (SPS). A comprehensive estimation of the microstructure properties, including room temperature fracture toughness, high strength oxidation resistance, a function Nb/Nb5Si3/Cr2Nb phase volume fraction combinations was conducted. The results showed that samples with relative density larger than 98.42% obtained SPS processing, all consisted...
High-throughput method of three targets magnetron sputter co-deposition was adopted to prepare (Nb–Ti)1-x-ySixCry composition spread alloy film (CSAF). Early oxidation behavior the as-deposited thin investigated in atmospheric conditions at 1250 °C for 10 min. A combinatorial material library covering (9.34–32.31) Si-(10.43–20.27) Cr (at. %) is obtained and composed amorphous phase. The oxidized separated into regions having different products. range establishment a protective scale (SiO2...
This paper deals with microstructural evolutions and mechanical properties of Nb–Si binaries containing dual-phase Nb/Nb5Si3 Nb to Nb5Si3 fraction ratios 90:10, 80:20, 70:30 50:50, prepared by spark plasma sintering (SPS). Dense samples a relative density larger than 99.5% were obtained SPS processing. The consist the phases less 3% NbO oxide. Hv at room temperature, compressive strength 1150 °C 1250 bulk alloys increase monolithically enhancing stiffening phase. For example, 0.2% yield...
