摘要
Co3Ti和Co3Ti-Fe合金在氢气环境中存在着严重的脆化现象Co3Ti合金中的Fe对合金在氢气中的脆化有延缓作用,但不能完全抑制环境氢脆.Co3Ti合金在氢气中的脆化机理与其在空气中的脆化机理不同.
The serious environmental embrittlement occured in Co3Ti and Co3Ti-Fe alloys when these materials were tested in hydrogen gas. The ductility of Co3Ti and Co3Ti-Fe alloy increases with the increase of strain rate, and the value of elongation of Co3Ti alloy is smaIler than that of Co3TiFe alloy at the same strain rate when tested in hydrogen gas. Fe can alleviate the embrittlement of Co3Ti alloy in gaseous hydrogen, but can not suppress it completely The mechanism of hydrogen embrittlement of Co3Ti alloy in gaseous hydrogen is different from that in air.
