增强体 TiB 和 TiC 在 Ti 中的原位生成

In Situ Formation of TiB and TiC Reinforcements in Ti

分析了增强体ＴｉＢ和ＴｉＣ在Ｔｉ中的原位生成原理，研究了利用Ｂ４Ｃ粉末与海绵Ｔｉ混合熔炼制备钛基复合材料的技术．结果表明，ＴｉＢ和ＴｉＣ以纤维状或树枝状的形式在Ｔｉ中生长，且分布均匀．

The pinciple of the in situ formation of TiB and TiC reinforcements in Ti is analysed.A new technology is explored to mix the B 4C particles and spongy Ti to fabricate the in situ(TiB+TiC)/Ti composite.The results show that the reinforcements of TiB and TiC are grown in fibrous and dendritic structures and their distributions are very uniform in titanium matrix.
