Through better understanding of the influence of field effects and varying spark plasma sintering processing parameters, it is easier to predict the required parameters for different types of materials and composites. In addition, it helps in determining the most efficient manufacturing technique for a material, leading to lower production costs while maintaining desired microstructure and mechanical properties. This study serves to clarify and determine the influence of field effects, through varying spark plasma sintering parameters, in relation to the resulting microstructure and mechanical properties of boron carbide. The influence of the field effects was determined through usage of different dies with varying conductivity (graphite, tungsten carbide, and alumina) and comparing the resulting relative densities and hardness of the samples. The effects of varying the current pulse on the resulting field effects was also studied. The samples were then characterized by scanning electron microscopy and micro-hardness testing.
