摘要
Creep resistance of two MoSi2-based materials containing SiC and HfO2 particles, respectively, in ambient atmosphere was studied in the temperature range 1100-1400 degreesC under a load of 100 MPa. The microstructure and its response to hi.-h-temperature load were investigated by TEM using the thin foil technique. Comparison of the creep resistance of both materials at each particular testing temperature shows that the performance of MoSi2-HfO2 is about one order of magnitude better than the other one.
