Abstract: Austenitic stainless steel includes 16 to 26 wt % of chromium (Cr), 8 to 22 wt % of nickel (Ni), 0.02 to 0.1 wt % of carbon (C), 0.2 to 1 wt % of niobium (Nb), and 2 to 3.5 wt % of manganese (Mn), and has an austenite matrix, wherein a nanosized niobium carbide (NbC) is precipitated in the austenite matrix, and the nanosized niobium carbide is uniformly dispersed in the austenite matrix. The austenitic stainless steel may further include 0.5 to 1.5 wt % of molybdenum (Mo).

Abstract: A method of fabricating a metal nanowire dispersion solution includes heating a first solution including a metal compound, a catalyst, an organic protection agent and menstruum, thereby forming metal nanowires in the first solution, performing a first cleaning process providing a first solvent into the metal nanowire, thereby separating the organic protection agent surrounding the metal nanowires from the metal nanowires, separating the metal nanowires from the first solution by vacuum-filtering, and dispersing the separated metal nanowires in a dispersion solvent.
