通过对钛板表面进行氧化处理,采用冷轧复合工艺制备TA1 P-Ti/AA6061复合板.结果表明:在TA1纯钛板表面制备的氧化膜(Ti6O)在冷轧过程中容易开裂,从而促进界面处形成有效的机械互锁,可有效地降低钛、铝板经冷轧后产生复合的最小压下率;此外,经氧化处理的复合板材的剪切强度得到提高,特别是在43％的压下率下,其剪切强度达到117 MPa.基于氧化处理和不同的冷轧压下率,经400、450和500 ℃退火后的复合板材均具有良好的界面抗分层能力,最大伸长率为31.845％,表现出优异的强度-塑性相容性.
Bonding enhancement of cold rolling TA1 P-Ti/AA6061 composite plates via surface oxidation treatment
TA1 P-Ti/AA6061 composite plate was produced by oxidizing the surface of the titanium plate and adopting a cold roll bonding process.The results revealed that the oxide film(Ti6O)prepared on the surface of TA1 pure titanium was easy to crack during the cold roll bonding,thereby promoting the formation of an effective mechanical interlock at the interface,which can effectively reduce the minimum reduction rate of the composite plates produced by cold rolling of titanium and aluminium plates.Moreover,the composite plate subjected to oxidation treatment exhibited high shear strength,particularly at a 43％reduction rate,achieving a commendable value of 117 MPa.Based on oxidation treatment and different reduction rates,the annealed composite plates at temperatures of 400,450,and 500 ℃ displayed favorable resistance to interface delamination,highlighting their remarkable strength-plasticity compatibility as evidenced by a maximum elongation of 31.845％.
