海报摘要

Analysis of the thermal runaway-driven flash event in tungsten carbide (WC) granular compacts. Finite element analysis (FEM) was implemented to study the heat balance contributing to the flash event of a conductive material like WC. The results obtained from such simulation coupled with the experimental findings confirmed the role of surface chemistry on the activation of flash sintering of materials with a positive temperature coefficient (PTC) for electrical resistivity.
