| Research Abstract |
Zr/SiC fiber composites were fabricated and the mechanical properties and corrosion resistance were examined. The addition of the SiC fiber effectively increased the elastic modulus and the creep strength. However, the corrosion properties strongly deteriorated.
Intermetallic compounds of Zr(Fe,Cr)2, Zr2(Fe,Ni) and bZr-Nb alloy were additionally examined. The bZr-Nb alloy had a property similar to aZr, and the alloy showed highest corrosion resistance.
