Description:
(abstract)This study investigated the high-temperature strength of spark plasma sintered tantalum diboride (TaB2) for the first time. TaB2 exhibited a unique elastic fracture behavior below 1900°C, unlike other transition metal diborides. The consolidation process involved spark plasma sintering at 2000–2200°C yielding dense TaB2 samples. The flexural strength was measured at elevated temperatures up to 2000°C, showing a quite high flexural strength of 400±20 MPa at 1900°C. These findings provide valuable insights into the high-temperature behavior of TaB2, highlighting its potential for advanced applications.
