This study is focused on the effect of vanadium addition to an API X100 steel.Laboratory heats were melted and control rolled based on a coil plate production process.Compared to non vanadium steel,it was found that 0.06%vanadium added steel had 8 to 14%higher yield and tensile strengths in all directions,while the toughness and ductility were similar for both steels.It is believed that the higher strength of the vanadium steel was partially due to its smaller grain size,larger fraction of sub grain boundaries and a higher number of uniformly distributed carbonitride precipitates in the vanadium steel.

由温室气体的过度排放引起的全球变暖问题日益严峻,努力实现对CO2的减排已是全球趋势。化学吸收法是碳捕集技术中最为成熟的技术之一,但在应用过程中的再生能耗较高,约占捕集总能耗的70%-80%,降低CO2的解吸能耗是降低化学吸收法捕集CO2成本的关键。相变化吸收剂由于能大幅度降低再生液量,具有降低解吸能耗的潜力,本实验室前期的研究发现,通过盐析效应和助溶效应可以进行相变化吸收剂的的开发,并成功开发了由
