dc.description.abstract将钇元素作为烧结助剂引入到聚碳硅烷(PCS)中制备含钇PCS。由含钇PCS制成SiC(OY)和SiC(Y)2种碳化硅纤维。对SiC(OY)纤维转变成SiC(Y)纤维的结构与相关特性的变化进行研究。SiC(OY)纤维的化学组成为SiC1.23O0.05Y0.005,纤维是无定型结构;SiC(Y)纤维含有大量的直径为50nm的β-SiC晶粒和少量的α-SiC晶粒,钇元素存在于SiC晶粒之间。SiC(OY)的拉伸强度为2.25GPa,断裂韧性为2.37MPa.m1/2;SiC(Y)的拉伸强度为1.61GPa,断裂韧性为1.91MPa.m1/2;SiC(Y)纤维比SiC(OY)纤维具有更好的热稳定性。zh_CN
