英文摘要	The hot-dip aluminizing-zinc process was used to pre-treat the low-carbon steel plates, and then the aluminum/low-carbon steel clad plates were successfully fabricated by liquid-solid twin-roll casting (LSTRC). The microstructure observation and interface combination of the clad plates were investigated by optical microscope (OM) and scanning electrical microscope (SEM), and the phase composition was measured by energy dispersive spectrometer (EDS) as well as X-ray diffractometer (XRD). In addition, with the mechanical properties of the clad plates were characterized by microhardness, room temperature tensile and shear tests. The results show that the interface gaps of the clad plates disappear and the overall trend of the thickness of the diffusion layer gradually increase when the covering temperature increasing. In the LSTRC process, when the pouring temperature is 710 and above, Fe3Al, FeAl, FeAl2, Fe2Al5 and FeAl3 phases are formed at the interface. At the same covering temperature, the overall microhardness trend is stable in the Q235 and A356 substrates, and the microhardness decreases continuously from Q235 side distance interface center about 100 μm to A356 side distance interface center about 100 μm. The tensile strength and shear strength of the clad plates increase firstly and decrease later. When the A356 covering temperatures is 710, the tensile strength and shear strength reach the highest value, which are 336.4 MPa and 137.6 MPa, respectively. © 2020, Science Press.
