Abstract : Test bars of zirconium Pyrocarbide containing an excess of Pyrographite were tested in flexure to 2000 C. The exceptional strength of this material increases with temperature to 2000 C where it begins to deform plastically indicating that it should be ideal in thermal shock resistance. Pellets of graphite with 20 percent additions of ZrC, TaC, and HfC heated to 3100 C showed no signs of melting. (Author)
