摘要/Abstract

摘要： 采用扩散连接的方法研究保温时施加塑性变形对2219铝合金界面愈合的影响机理。在扩散温度545 ℃,保温时间4 h,压力10 MPa,选取塑性变形量为0%、10%、30%、50%进行扩散连接试验。结果表明,随着塑性变形量增大,界面处于高能量状态,溶质原子在界面处通过扩散析出Al₂Cu相,包裹原始的界面氧化物并在保温与变形过程中发生冶金反应,氧化物分解并向基体扩散直至消失,实现界面愈合;结合强度在塑性变形量为50%时最高,达到116 MPa,为基体材料的90.6%。

Abstract: Effect mechanism of plastic deformation on interface bonding of 2219 aluminum alloy by applying plastic deformation during holding was studied by diffusion bonding method. The diffusion bonding test was carried out at the diffusion temperature of 545 ℃, the holding time of 4 h, the pressure of 10 MPa with the plastic deformation of 0%, 10%, 30% and 50%. The results show that with the increase of plastic deformation, the interface is in a high energy state. The Al₂Cu phase at the interface is precipitated by solute atom diffusion, which encapsulates the original interface oxide and undergoes metallurgical reaction with oxide during heat preservation and deformation. The oxide decomposes and diffuses to the matrix till it disappears, achieving interface healing. The bonding strength reaches up to 116 MPa with plastic deformation of 50%, which is 90.6% of the base material.
