Free graphite containing powders

A method of manufacturing a material, comprising the step of:

• atomizing an iron-based composition to form a powder metal, the iron-based composition including carbon (C) in an amount of 5.0 wt. % to 6.5 wt. % and silicon (Si) in an amount of 0.1 wt. % to 6.0 wt. %, based on the total weight of the powder metal, the powder metal optionally including at least one of nickel (Ni), cobalt (Co), copper (Cu), tin (Sn), aluminum (Al), sulfur (S), phosphorous (P), boron (B), nitrogen (N), chromium (Cr), manganese (Mn), molybdenum (Mo), vanadium (V), niobium (Nb), tungsten (W), titanium (Ti), tantalum (Ta) zirconium (Zr), zinc (Zn), strontium (Sr), calcium (Ca), barium (Ba) magnesium (Mg), lithium (Li), sodium (Na), and potassium (K).

A method of manufacturing a material, comprising the step of:

• atomizing an iron-based composition to form a powder metal, the iron-based composition including carbon (C) in an amount of 2.0 wt. % to 5.0 wt. %, silicon (Si) in an amount of 0.1 wt. % to 2.5 wt. %, and at least one of the following:
• nickel in an amount of 4.0 to 46 wt. %, cobalt in an amount of 0.1 to 46 wt. %, copper in an amount of 3.0 to 40 wt. %, tin an amount of 0.1 to 15 wt. %, aluminum in an amount of 0.1 to 10 wt. %, sulfur in an amount of 0.05 to 2.0 wt. %, phosphorous in an amount of 1.0 to 2.0 wt. %, boron in an amount of 0.20 to 1.0 wt. %, nitrogen in an amount of 0.05 to 1.0 wt. %, chromium in an amount of 2 to 25 wt. %, manganese in an amount of 2 to 25 wt. %, molybdenum in an amount of 4 to 10 wt. %, vanadium (V) in an amount of 0.1 to 10 wt. %, niobium (Nb) in an amount of 0.1 to 10 wt. %, tungsten (W) in an amount of 0.1 to 20 wt. %, titanium (Ti) in an amount of 0.1 to 10 wt. %, tantalum (Ta) in an amount of 0.1 to 10 wt. %, and zirconium (Zr) in an amount of 0.1 to 10 wt. %, based on the total weight of the powder metal, and the powder metal optionally including at least one of zinc (Zn), strontium (Sr), calcium (Ca), barium (Ba), magnesium (Mg), lithium (Li), sodium (Na), and potassium (K).
