Research of the interface microstructure and thermal treatment of cold-rolled Cu-Al composite strip under magnetic field

摘要：

　　The thermal treatment process of cold-rolled Cu-Al composite strip under magnetic field conditions is systematically investigated by means of metallographic microscope and universal testing machine to observe the interface microstructure and test the mechanical properties.The heat treatment parameters effects to the interface structure and mechanical properties of Al-Cu cold-rolled strip are discussed.The conclusions is showed as follows:(1)when the magnetic field intensity is greater than 0.1 T,the interface layer grow widely and stimulate the interfacial compounds generation,the shear strength is reduced.(2)When the Cu-Al specimens annealing temperature is at the condition of 300 ℃,the interfacial layer narrows when the magnetic field strength stay 0.1T than that without magnetic field,the magnetic filed restrains the interfacial compounds generation,the shear strength reaches as high as 124Mpa;(3)The interfacial compounds are meanly brittleness intermetallic compounds such as CuAl、CuAl2、Cu9Al4.
