HV-KIC property charts of cemented carbides: A comprehensive data collection

In this work more than 2500 published experimental data on hardness and indentation fracture toughness of cemented carbides during the last 40 years have been collected. The significant number of samples displays the influence of microstructure, chemical composition, and processing on the hardness - toughness relationship of cemented carbides. Selected two-dimensional plots are presented and discussed as an example of visualization of the available experimental information. This collected record can serve as an initial reference set for the cemented carbide community using all available shared knowledge organized in one well-structured database.

Automated summary

This study collected over 2500 published experimental data on the hardness and indentation fracture toughness of cemented carbides in the past 40 years, illustrating the influence of microstructure, chemical composition, and processing on the hardness-toughness relationship. Two-dimensional plots were used for visualizing the experimental information, serving as a well-structured database for the cemented carbide community.
