| Abstract Scope |
Tool steels are key materials in applications where a combination of wear resistance, and toughness is required. Toughness and wear resistance in tool steels are often in tension as wear resistance is largely controlled by the hard phase (carbide/nitride) volume, which is inversely correlated with toughness. In this study, we seek to examine the viability of using powder mixing methods to develop a ferrous metal matrix composite with a hard phase that is both finer, and harder than the carbides found in powder metallurgy tool steels. To do so, it is vital to achieving a consistent dispersion of hard phase particles throughout the material. With that in mind, we analyzed the dispersion of hard phase particles in 12 iron powder samples with 2.5-10% volumes of 0.5-1.5µm or 1-3µm particles after mixing them for 15 or 60 minutes in a shaker-type ball mill. |
