“…12 and 20, the higher Cr content was found to lead to smaller intragranular carbide precipitation depth in both ferritic and austenitic alloys at both temperatures. This is consistent with [19,20] expressed in Equation 5 and 6.…”

“…The cast samples were, then, annealed in a flowing argon-5%H2 gas atmosphere at 1050℃ for 70 h and cooled with the furnace to homogenize the samples. An analysis by X-ray diffraction (XRD) revealed that Fe- (10,20,25)Cr were ferrite while Fe-20Cr- (20,33)Ni and Fe-25Cr-20Ni were austenite. Compositions of the alloys were confirmed by SEM-EDS analysis after annealing, showing only small deviations (± 0.3 wt.…”

Metal dusting behaviours of Fe-(10, 20, 25)Cr, Fe-20Cr-(20, 33)Ni, Fe-25Cr-20Ni (wt.%) in a Ar-33CO-7H2-7CO2-2H2O (vol.%) gas at 550℃ and 650℃ were investigated in simulating a blast furnace operating condition. Severe metal dusting and coke deposition were observed at 550℃, while no significant dusting but internal oxidation and carburization were observed at 650℃. Higher Cr and Ni contents in the alloy lowered kinetics of metal dusting at 550℃ and of carburization at both temperatures. In particular, Fe-25Cr was the only alloy exhibiting no significant metal dusting at 550℃. Increasing Cr concentration also reduced oxidation kinetics at both temperatures. Austenitic alloys were more susceptible to metal dusting and coke deposition than ferritic alloys with the same Cr content at 550℃. At 650℃, however, ferritic alloys experienced higher extents of carburization and oxidation than austenitic alloys with the same Cr concentration.

Exploring the landscape of seasonal forecast provision by Global Producing Centres

et al. 2022

Despite the growing demand for seasonal climate forecasts, there is limited understanding of the landscape of organisations providing this critically important climate information. This study attempts to fill this gap by presenting results from an in-depth dialogue with the organisations entrusted with the provision of seasonal forecasts by the World Meteorological Organisation, known as the Global Producing Centres for Long-Range Forecasts (GPCs-LRF). The results provide an overview and detailed description of the organisational setup, mandate, target audience of GPCs-LRF and their interactions with other centres. Looking beyond the GPCs-LRF to other centres providing seasonal forecasts, some of which have been rapidly taking prominent places in this landscape, revealed a heterogeneous and still maturing community of practice, with an increasing number of players and emerging efforts to produce multi-model ensemble forecasts. The dialogues pointed at the need to not only improve climate models and produce more skilful climate forecasts, but also to improve the transformation of the forecasts into useful and usable products. Finally, using the lenses of credibility, salience and legitimacy, we explore ways to bridge the fragmentation of the information offered across the organisations considered and the people involved in the delivery and use of seasonal forecasts. The paper concludes by suggesting ways to address the boundary crossing between science, policy and society in the context of seasonal climate prediction.
