摘要
采用热轧复合工艺生产4343/3003/7072铝合金钎焊板,利用光学显微镜、电子拉伸试验机和扫描电镜,研究了铝合金钎焊板的包覆率、显微组织和力学性能。结果表明,铝合金钎焊板的包覆层合金厚度均匀、复合界面平整,铝合金钎焊板中4343和7072铝合金包覆层的包覆率分别为9.0%和8.1%,铝合金钎焊板的抗拉强度、屈服强度和伸长率分别为118.62 MPa、56.21 MPa和32.48%。
The paper highlighted cladding rate,microstructure and mechanical properties of 4343 /3003 /7072 aluminum alloy brazing sheet manufactured by hot roll bonding using OM,SEM and electronic tensile testing machine; The results indicated that the clad thickness was uniform and the composite interface was smooth,with cladding rate of 4343 and 7072 clad alloy reaching 9. 0% and 8. 1%,respectively; the tensile strength,yield strength and elongation of the aluminum alloy brazing sheet were 118. 62 MPa,56. 21 MPa and 32. 48%,respectively.
