    摘要:

    针对钛/不锈钢不易直接热轧复合的问题,通过添加工业纯铁为中间层材料,采用真空轧制的方法制得钛合金/不锈钢复合板。利用扫描电子显微镜、能谱仪、X射线衍射仪和拉剪实验,研究纯铁中间层和不同温度对复合板界面组织特征和性能的影响。结果表明:添加纯铁中间层后,在轧制温度为750~950℃、压下率为20%时,随着轧制温度的升高,复合面剪切强度增加,在轧制温度为950 ℃时,复合效果最好,复合界面剪切强度达到248 MPa;在高温1 050 ℃时,纯铁和钛合金的交界面上生成β-Ti和Fe2Ti化合物会降低复合强度。

    Abstract:

    In view of the problem that TC4/304 are difficult to be directly bonded by hot-roll, a TC4/304 composite plate was prepared by hot-roll bonding in a vacuum using a DT4 interlayer. The effects of the DT4 interlayer and the bonding temperature on the mechanical properties and interfacial structure of the composite plate were investigated by scanning electron microscopy, energy spectrometry, X-ray diffractometer and tensile-shear testing. The results show that, when the intermediate layer of DT4 is added, at a 20% reduction ratio, when the bonding temperature is between 750 ℃ and 950 ℃, the shear strength of the bonding surface increases with the increase of the bonding temperature. At 950 ℃, the bonding effect is best, the shear strength of the bonding interface reaches 248 MPa. At 1 050 ℃, formation of intermetallic compounds at the interface between DT4 and TC4 decreases the bonding strength.
