a Fitted XRD patterns of the polished sample surface before compressive testing and the fracture surface after compressive testing for the (WTaNbZrTi)C HEC sintered at 50 MPa. Source data are provided as a Source Data file. b Schematic diagram showing the crack propagation and the transformed ZrO2 particles on the cracked surfaces. The gray arrow in b points to the direction of crack propagation.
