“…After the gases in the chamber were evacuated, the chamber was continuously filled with ultra-pure argon gas (≥99.999 %) to prevent the oxidation of the sample surface. It should be noted that the solidification of a sample has commenced below the surface of the opaque melt and is gradually being revealed on the melt surface because the thermocouple is in contact with the bottom of the alumina crucible [8,23]. Therefore, the temperature difference between the surface of the sample and thermocouple should be taken into account in the experiment.…”

“…Generally, a more refined secondary dendrite spacing is desirable. According to Ahmadetal et al [15], SDS depends on the composition and existence of additive elements, which is used to describe the scale of columnar dendritic structures [16].…”

“…Confocal scanning laser microscopy (CSLM) is a powerful method for investigating the solidification processes of low-carbon steels, stainless steels, and metallic glasses. [9][10][11][12] Because C is regarded as an austenite-forming element, increasing its content in X10CrAlSi18 FHSS may facilitate austenite transition during the solidification. [13] As a result, using CSLM to examine the microstructure evolution of X10CrAlSi18 FHSS during the solidification process may not only give in situ data support but also provide a theoretical foundation for accomplishing solidification structure control.…”
