4343/3003/4343 aluminum 4343 alloy properties ingots have been prepared by liquid-solid casting. The microstructure, elements distribution and interface bonding strength from the clad ingots had been investigated. The interface bonding mechanism of your clad ingots was analyzed. The outcomes show the moment the pouring temperature of 4343 aluminum alloy is 725-750℃, the metallurgical bonding of clad ingots is excellent, in accordance with clear and flat interface.
The metallurgical bonding interface of clad ingots consists of 4343 aluminum 4343 alloy properties Al-Si strong remedy layer and diffusion layer of Si and Mn. The thickness of Al-Si solid solution layer is uniform. The diffusion distances of Mn and Si are 10μm and 32μm, respectively.The bonding strength of clad ingots is higher than the ultimate tensile strength of 3003 aluminum alloy.
The interface bonding mechanism of liquid-solid 4343/3003/4343 aluminum alloy clad ingot is as follows:firstly, the
melt is quickly solidified on the the surface of 3003 aluminum alloy ingot to kind the Al-Si solid solution layer, then the Si inside the Al-Si solid remedy layer and the Mn inside the 3003 aluminum alloy interdiffused to kind the clad ingot with great metallurgical bonding interface.
