Abstract: A thermometric powder metal material for testing to replicate an actual powder material during use of the actual powder metal material in an internal combustion engine is provided. The thermometric powder metal material includes pores and has a decrease in hardness as a function of temperature according to the following equation: D Hardness / D Temperature = > 0.5 HV/°C. The properties of the actual powder metal material, when the actual powder metal is used in an internal combustion engine, can be estimated using the thermometric powder metal material by first adjusting the thermal conductivity of the thermometric powder metal material or controlling the porosity of the thermometric powder metal material to replicate the actual powder metal material, and then subjecting thermometric powder metal material to an engine test. For example, the thermal conductivity can be adjusted by infiltrating the thermometric powder metal material with copper.

Abstract: An improved method of manufacturing a cast part by sand casting, permanent mold casting, investment casting, lost foam casting, die casting, or centrifugal casting, or a powder metal material by water, gas, plasma, ultrasonic, or rotating disk atomization is provided. The method includes adding at least one additive to a melted metal material before or during the casting or atomization process. The at least one additive forms a protective gas atmosphere surrounding the melted metal material which is at least three times greater than the volume of melt to be treated. The protective atmosphere prevents introduction or re-introduction of contaminants, such as sulfur (S) and oxygen (O2), into the material. The cast parts or atomized particles produced include at least one of the following advantages: less internal pores, less internal oxides, median circularity of at least 0.60, median roundness of at least 0.60 and increased sphericity of microstructural phases and/or constituents.

Abstract: An improved atomized powder metal material containing an increased amount of free graphite after heat treatment and/or sintering is provided. The powder metal material is typically a ferrous alloy and includes carbon in an amount of 1.0 wt. % to 6.5 wt. % and silicon in an amount of 0.1 wt. % to 6.0 wt. %, based on the total weight of the powder metal material. The powder metal material can also include various other alloying elements, for example 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).
