Abstract Scope |
Novel SiAlON/TiCN composites are computationally designed and then synthesized intended for cutting tools followed by machining performance evaluation using the finite element method. The design and optimization of the volume fractions, the interfacial thermal resistance, and the sizes of the reinforcement particles are done using the effective medium theories and mean-field homogenization approaches, considering the impact of porosity on the effective thermomechanical properties of composites. The spark plasma sintering process is used to produce the designed composites followed by characterization. The stand-alone Al2O3 and designed SiALON/TiCN tools are then considered to quantitatively examine the thermomechanical behavior during the cutting simulation of superalloys. The simulated temperature distribution on the surfaces of the tool, workpiece, and chip are captured during cutting superalloys. It was found that the designed SiALON/TiCN tool resulted in lower temperature levels and improved mechanical response as compared to the commercially available Al2O3 tool. |
