    摘要:

    采用定容變壓法測定不同初始?xì)浞謮合耇i600合金的吸氫動(dòng)力學(xué)特性，研究不同氫含量下的微觀組織。結(jié)果表明，隨著氫含量的增加，初生α相和β相的形狀、大小、分布及兩相的比例均發(fā)生變化，Ti600合金的微觀組織變得模糊，α相與β相相界模糊。Ti600合金在750 ℃下置氫時(shí)，吸氫過程只表現(xiàn)為第2吸氫階段。在初始吸氫階段，其Avrami指數(shù)n＞1，表現(xiàn)為多級反應(yīng)；充氫結(jié)束后200 s時(shí)，氫化反應(yīng)的Avrami指數(shù)n接近1，說明氫在合金內(nèi)的擴(kuò)散是氫化反應(yīng)的速率控制步驟

    Abstract:

    The kinetics of hydrogen absorption for Ti600 alloy is studied at different initial hydrogen pressures using a constant volume method. The microstructure of hydrogenated Ti600 alloy at different hydrogen contents is observed. It is found that the shape, size, distribution and ratio between primary α phase and β phase change and the microstructure of hydrogenated Ti600 alloy and the phase boundary become ambiguous. The hydrogen absorption process represents only the second stage for the Ti600 alloy during hydrogenating at 750 ℃. The hydrogenating reaction represents multilevel reaction with the Avrami index of n>1 for the initial stage. The Avrami indices reach 1 after hydrogen absorption for 200 s, which illustrate that the rate limit of hydrogenating reaction is due to the diffusion of hydrogen in alloy
