Abstract
Polycrystalline TiB 2 specimens of 3 μm average grain size but free of lamellar precipitates were compression‐tested to 1900°C and 500 MPa. No plastic yielding was detected. Under such conditions, most other structural ceramics do exhibit yield behavior. The results suggest the existence of a high Peierls stress, presumably related to Ti—B bonding. This finding contrasts with a report on ZrB 2 in which resistance to yielding was attributed to lamellar precipitates.Keywords
