Abstract: Disclosed herein are embodiments of iron-based corrosion resistant hardfacing alloys. The alloys can be designed through the use of different compositional, thermodynamic, microstructural, and performance criteria. In some embodiments, chromium content in the alloy can be increased while avoiding the formation of different hard chromium carbides, thereby increasing the corrosion resistance of the alloy.

Abstract: A hard weld overlay which is resistant to cracking when re-heated, and a method for designing such alloys, is disclosed. The alloys are able to resist re-heat cracking through prevention of the precipitation and/or growth of embrittling carbide, borides, or borocarbides at elevated temperatures. In one embodiment, the thermodynamics of the alloy system possess only primary carbides and secondary ferrite carbides.

Abstract: Disclosed herein are embodiments of a hard weld overlay which can be resistant to cracking. The alloys can be able to resist cracking through prevention of the precipitation and/or growth of embrittling carbide, borides, or borocarbides along the grain boundaries at elevated temperatures. By controlling the thermodynamics of the boride and carbide phases, it is possible to create an alloy which forms hard wear resistant phases that are not present along the grain boundaries of the matrix.
