Discussion on determination method for microstructure of 2A12 aluminum alloy based on cross section polisher and electron back scattering diffraction
The conventional method for microstructure inspection of aluminum alloy is mainly metallograph-ic method.However,this method is complicated in operation,easy to misjudge the slightly overburnt structure,and the grain display effect is not ideal,which has certain limitations.In order to analyze the microstructure of aluminum alloy more conveniently and accurately,the determination method for micro-structure of 2A12 aluminum alloy was systemically investigated based on cross section polisher(CP)and e-lectron back scattering diffraction(EBSD).The results show that compared with the conventional metallo-graphic method,the burnt microstructure of aluminum alloy processed by cross section polisher could be determined sensitively and accurately under the optical microscope without corrosion,and the phase and grain size could be further analyzed accurately by electron backscattering diffraction.
