The results show that the boron doping in Co3Ti does not have the effect on suppressing environmental embrittlement. The hydrogen diffusion coefficients in Co3Ti alloys with and without boron measured by a new experimental method have almost the same value, which indicates that boron in Co3Ti alloys does not reduce the hydrogen diffusivity along the grain boundaries. The susceptibility of boron-doped Co3Ti alloys to moisture-induced environmental embrittlement is attributed to no boron atoms segregating to the grain boundaries. Key words:  Co_3Ti      environmental embrittlement      hydrogen diffusivity      Received:  18 February 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I2/141 1George E P,Liu C T,Pope D P.Scripta Metall,1993;28:875 2 Wan X J, Zhu J H, Jing K L.
