Abstract
Cemented carbide materials are key in tool manufacturing, nowadays widely used in cutting, forming and other manufacturing processes. Commonly applied methods for obtaining their strain-rate dependent material properties are insufficient due to the high hardness, mechanical strength and low deformability. In this paper, we produce relevant data for stress-strain and strain-rate curves up to strain rates of approximately 200 s−1 with the aid of a developed FEM-supported evaluation method for remaining imprints on cemented carbide surfaces after applying impact loads at various durations and magnitudes. Regarding the impact duration, the impact loads were dynamically generated via electromagnetic or piezoelectric devices. The attained data are relevant to several applications including calculations to determine the stress and strain fields developed in cemented carbide tools imposed by impact loads at various conditions.
