Abstract

Cemented carbide is often used as the pick-tip material for conical picks. The pick-tip often experiences premature failure due to insufficient toughness. This paper aims to improve the impact toughness of cemented carbide through electromagnetic coupled cryogenic treatment. A theoretical model between process parameters and impact toughness is established. The optimal parameters are determined as follows: a cryogenic temperature of −190 °C, cryogenic time of 24 h, magnetization intensity of 1.5 T, and magnetization time of 15 s. The treatment improves the impact toughness by 11.39% compared with the heat treatment. Microstructure analysis indicates a notable increase in dislocations and grain refinement within the Co phase, attributing to the enhanced toughness.
