摘要/Abstract

摘要： 对Ti-10Mo(质量分数,%)合金拉伸预变形诱发的{332}<113>孪晶和α″马氏体的演变进行了研究,利用XRD、EBSD、维氏硬度计及万能试验机等手段,对预变形组织和时效处理后析出的等温ω相对其力学性能的影响进行了讨论。结果表明,分别在200~400 ℃下对固溶处理的合金时效处理1 h,硬度显著增加。在20%预变形量、250 ℃×1 h时效条件下,合金的屈服强度较高,为844 MPa,其均匀延伸率较好,为13%。由拉伸预变形诱发的孪晶和α″马氏体的组织演变对等温ω相的析出影响较小。孪晶、马氏体和等温ω相的耦合作用使得合金的强度和塑性得到提高。合金较高的屈服强度主要归因于等温ω相在时效过程中从基体中析出,使得变形初期的塑性变形方式由位错滑移主导,合金良好的均匀伸长率主要归因于预变形诱发孪晶和α″马氏体的细化效应。通过合理的预变形与热处理制度调控β型钛合金的塑性变形方式和相析出行为,可在较大范围内调控其力学性能。

Abstract: Evolution of pre-strain induced {332}<113> twins and α″-martensite in the deformation microstructure of Ti-10Mo alloy (mass fraction, %) was investigated, the effect of those evolution combined with isothermal ω-phase after subsequent aging on the mechanical properties was discussed by means of XRD, EBSD, Vickers hardness tester and universal testing machine. The results demonstrate that the hardness of solution treated specimens increases significantly after aging at 200-400 ℃ for 1 h. The higher yield strength and larger uniform elongation of the alloy with 20% pre-strain combined with subsequent 250 ℃×1 h aging are 844 MPa and 13%, respectively. The effect of pre-strain induced twins and α″-martensite on the precipitation of isothermal ω-phase is negligible. The alloy exhibits improved strength and ductility by the coupling effects of twin, α″-martensite and isothermal ω-phase. The high yield strength is mainly dominated by the isothermal ω-phase precipitation, which leads to dislocation slip domination in the early onset of plastic deformation, and the large uniform elongation is due to the refinement effect of pre-strain induced twins and α″-martensite. These results indicate that by controlling the transition of plastic deformation mode and the evolution of phase precipitation behavior in the β-type titanium alloys through reasonable pre-deformation and heat treatment, the mechanical properties can be controlled in a larger range.
