Keywords： Composite material

A new composite material consisting of lxxx aluminum alloy and 7xxx aluminum alloy was produced by semi-continuous casting.Macrostructure,microstructure,composition distribution and hardness distribution of composite interface were analyzed.Macrostructure shows that composite interface is planar and clean with little evidence of porosity; microstructure shows that composite interface is a kind of metallurgical bonding; composition and hardness distributions have a good corresponding relationship.At the same time,the mechanical property of composite interface was measured,the tensile strength is 71 MPa,the shearing strength is 62 MPa and the bending strength is 142.5 MPa,which can also show that composite interface is a kind of metallurgical bonding.Temperature distribution of composite interface was obtained by measuring temperatures near composite interface in lxxx aluminum alloy.
