摘要
用Al部分替代V_(90)Ti_(10)氢分离合金中的V,研究Al含量对V_(90-x)Ti_(10)Al_(x)(x=0、2、5、10、15)合金显微组织、力学性能及轧制性能的影响。结果表明,V_(90)Ti_(10)合金组织为单相V基固溶体,其余四种合金均由V基固溶体和少量Al_(2)O_(3)相组成。随着Al含量的增加,晶粒逐渐细化,晶格常数逐渐增大,Al_(2)O_(3)含量增加且形态趋向粗化。当Al含量由2%持续添加至15%时,合金塑性与轧制性能持续下降,硬度持续升高,抗拉强度先增加后降低。V_(88)Ti_(10)Al_(2)综合性能最优,抗拉强度、延伸率、轧制极限压下率分别为531.1 MPa、7.73%、67.5%,与V_(90)Ti_(10)合金相比,硬度和强度分别提高7.1%与20.8%,延伸率与极限压下率分别降低1.36%与4%。
The impacts of substituting Al for V in the V_(90)Ti_(10)hydrogen separation alloy on the microstructure,mechanical properties,and rolling performance of V_(90-x)Ti_(10)Al_(x)(x=0,2,5,10,15)alloys were studied in this paper.The results show that V_(90)Ti_(10)is a single-phase V-based solid solution,while the other four alloys consist of V-based solid solutions and fewer Al_(2)O_(3) phases.As the Al content increases,the grain size decreases,the lattice constant increases,and Al_(2)O_(3) content increases and coarsens.As the Al content increases from 2%to 15%,there is a consistent decline in the alloy's ductility and rolling performance,alongside a continuous increase in hardness,The tensile strength initially rises but subsequently diminishes.V_(88)Ti_(10)Al_(2) exhibits the best overall performance with tensile strength,elongation,and ultimate compression rate measured at 531.1 MPa,7.73%,and 67.5%,respectively.Compared to V_(90)Ti_(10),its hardness and strength increased by 7.1%and 20.8%,elongation and ultimate compression rate decreased by 1.36% and 4%.
