钒钛微合金搪瓷钢中析出相和贮氢性能的研究

摘要

Precipitates in enamel sheets containing vanadium and both vanadium and titanium respectively as well as the effect of the precipitates on hydrogen storability of the sheets were investigated under the same rolling and annealing conditions .The results indicate that the precipitate is largely V ( C,N) in the sheet containing vanadium , whereas the precipitates are Ti ( C,N) , V( C,N) and Ti4 C2 S2 in the sheet containing both vanadium and titanium . The sheet containing both vanadium and titanium is superior to the sheet containing vanadium in the hydrogen storability .%在相同的轧制和退火工艺条件下，研究了含V和含V、含Ti搪瓷钢的析出相及其对钢的贮氢性能的影响。结果表明，含V钢的析出相主要为V（C，N），而含V、含Ti钢的析出相主要为Ti（C，N）、V （ C，N）和Ti4 C2 S2，含V、含Ti搪瓷钢的贮氢性能优于只含V的搪瓷钢。
