Creep behaviour of MoSi2-HfO2 composites

Several ways of improving the performance of MoSi2based composites have been developed by incorporating SiC and ZrO2 particles or SiC whiskers into the matrix. During the last decade, a number of papers have been dedicated to the study of creep behaviour of MoSi2-based materials, mainly in compressi...

Description
Summary:Several ways of improving the performance of MoSi2based composites have been developed by incorporating SiC and ZrO2 particles or SiC whiskers into the matrix. During the last decade, a number of papers have been dedicated to the study of creep behaviour of MoSi2-based materials, mainly in compression and tensile loading mode. The aim of this work was to investigate the creep resistance of the MoSi2-HfO2 materials in air at temperatures above 1100 DGC. After preliminary bending strength tests the samples were tested in bending in the temperature range 1100-1400 DGC under a load of 100 MPa.
