摘要：

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 & DEG;C, unlike other transition metal diborides. The consolidation process involved spark plasma sintering at 2000-2200 & DEG;C yielding dense TaB2 samples. The flexural strength was measured at elevated temperatures up to 2000 & DEG;C, showing a quite high flexural strength of 400 & PLUSMN; 20 MPa at 1900 & DEG;C. These findings provide valuable insights into the high-temperature behavior of TaB2, highlighting its potential for advanced applications.
