Abstract: Abstract Chemical vapor-infiltrated self-healing SiC(f)/BN(i)/[SiC-B4C](m) composite specimens were exposed at 1300 °C for 300 h at atmospheric pressure under two different oxidizing atmospheres (i.e., wet (12%H2O:8%O2:80%Ar) and dry (0.01%O2:99.99%Ar)) representative of rich and poor oxidizing conditions, respectively.… read more here.

Abstract: In this study, we investigated the effect of adding two different intermetallics, Ti5Si3 and TiSi2, for the preparation of TiB2-SiC-B4C composites. As part of the research, stoichiometric composites consisting only of two phases TiB2 and… read more here.
