Disclosed herein are iron-based alloys having a microstructure comprising a fine-grained ferritic matrix and having a 60+ Rockwell C surface, wherein the ferritic matrix comprises <10 μm Nb and W carbide precipitates. Also disclosed are methods of welding comprising forming a crack free hardbanding weld overlay coating with such an iron-based alloy. Also disclosed are methods of designing an alloy capable of forming a crack free hardbanding weld overlay, the methods comprising the steps of determining an amorphous forming epicenter composition, determining a variant composition having a predetermined change in constituent elements from the amorphous forming epicenter composition, and forming and analyzing an alloy having the variant composition.
An Fe-based alloy, wherein the alloy comprises, in wt. %
A wear resistant coating, comprising an Fe-based alloy comprising, in wt. %:
A method of forming a wear resistant coating, comprising depositing an Fe-based alloy on a substrate via a thermal spray process, said wear resistant coating comprising an Fe-based alloy comprising, in wt. %:
