1. A material comprising a composite comprising an amorphous metal ceramic composite comprising an iron-based amorphous metal alloy and a ceramic formed from the iron-based amorphous metal alloy,
wherein the composite exhibits a higher corrosion resistance than that of a Haynes 230 alloy when immersed in a molten chloride salt comprising KCl and MgCl2 in a ratio of 68/32 for 300 hours at a temperature of 750° C.;
wherein the iron-based amorphous metal alloy is fully amorphous up to 650° C. and starts to crystallize at a temperature higher than 650° C., and
the ceramic comprises a boride and a carbide;
wherein the iron-based amorphous metal alloy comprising Fe100-(a+b+c)(CraXbYc); wherein a is about 10 to 50 wt. %; b is between 0 to 30 wt. %, and c is between 0 to 10 wt. %; wherein X and Y are elements, and X is selected from the group consisting of molybdenum, copper, cobalt, aluminum, titanium, tungsten, niobium, silicon, vanadium, and combinations thereof, and Y is selected from the group consisting of boron, carbon, silicon, and combinations thereof.
