摘要
将Q345钢板与TAl钛板组坯抽真空后轧制成钛-钢复合板,对不同累积压下量复合板的性能进行了研究。结果表明:较低的累积压下量不利于新生表面的形成,使得复合板的结合性能不良;随着累积压下量的增大,复合板界面处的TiC及铁钛金属间化合物发生破碎、分散,复合板性能提高;累积压下量为90%复合板的抗剪强度为169 MPa,抗拉强度达到560 MPa,伸长率达到34.5%,冷弯结合度均达到了100%。
Q345 steel plate and TA1 titanium plate were assembled and vacuumized to prepare titanium-steel compound plate, and the interracial properties of commpound plates with different cumulative rolling reductions were studied. The results show that the lower reduction was harmful for the fresh surface forming and made bonding properties bad. The TiC and Fe-Ti intermetallic compounds broke and scattered with the increase of cumulative rolling reduction, and the propertices of the compound plate. The shear strength, tensile strength, elongation and cold bended combination strength of the compound plate with cumulative rolling reduction of 90% were 169 MPa, 560 MPa, 34.5% and 100%, respectively.
