“…Pressure, as an important thermodynamic parameter, shows significant effects on chemical reaction involving gas phase reactant or product, such as increasing reaction rate and solubility of gas or volatile element. 8,9) In addition, pressure also affects the solidification process. 10) On the one hand, increasing pressure could decrease the heat resistance at ingot/mould interface and enhance the cooling rate of ingots, providing a fine solidification structure.…”

EETU-PEKKA HEIKKINEN, TIMO FABRITIUS, and JAANA RIIPIThe criteria for evaluating the applied fields of science often are based on practical justifications such as functionality and applicability instead of objectiveness or truthfulness, which typically are emphasized in the more theoretical fields of science. The use of practical justifications is understandable when considering the value of an applied field of science, but it should be noted that this kind of approach leaves out some aspects that should be covered while considering the nature and meaning of the fundamental concepts of a certain field. This article analyzes the concept of process metallurgy from different perspectives and proposes a model that helps show the characteristic features and connections of the different aspects of the process metallurgy. Conceptual analysis was used to evaluate research concerning the modeling of the argon oxygen decarburization process, and it was concluded that holistic analysis of the fundamental concepts has certain advantages also on a practical level; it helps to visualize the connections among research, education, and practical applications as well as the links among different areas of research or education. With the awareness of these connections, it is easier to plan, visualize, and evaluate the research and its goals, methods, results, extent, and need for competence and to perceive the relations among the different areas of research as well as among the different researchers and to evaluate the validity of the research.

“…[1][2][3][4] As such, a series of typical HNSs have been developed recently, such as CRONIDUR 30, M340, P900N and P2000. 5,6) However, the beneficial influence of nitrogen is usually limited by its low solubility in some steels, 3,4) which can result in serious nitrogen segregation and nitrogen pore defect during the melting and solidification of HNSs.…”

The effect of solidification pressure (0.5, 0.85 and 1.2 MPa) on heat transfer between ingot and mould was investigated with the measurement of cooling curves and calculation of heat transfer coefficient. Combined with cooling rate, temperature gradient and local solidification time (LST), the influence of pressure on solidification structure of 19Cr14Mn0.9N was revealed by macrostructure observation. The calculation results of heat transfer coefficient, obtained by the Beck-Nonlinear estimation technique, indicate that increasing solidification pressure obviously enhances heat transfer at the ingot/mould interface. And higher solidification pressure is benefit to increase cooling rate and temperature gradient of ingot. Meanwhile, increasing solidification pressure considerably suppresses nitrogen gas pore, and reduces the whole area of dispersing porosity and shrinkage, which is favorable to obtain a sound ingot. With the solidification pressure increasing from 0.5 to 1.2 MPa, the columnar zone is lengthened, the columnar-toequiaxed transition (CET) position gradually moves to the ingot center, and both dendritic arm spacing (λ 1 and λ 2 ) and local solidification time (LST) gradually decrease. The solidification structure is significantly refined and compressed under higher solidification pressure.
