Study of the Mechanism of LF6 Aluminum Alloy Superplastic Deformation
Yuan Zizhou; Yang Jun
With the secondary duplicated model structure with high magnification, the surface grain structure of LF6 aluminum alloy superplastically deformed is observed. The deformation percentages of GBS(grain boundary sliding), DC(diffusion creep) and DS(dislocation sliding)—the three kinds of deformation mechanism under different deformation rate generally recognized at present are measured and calculated respectively. Based on the calculation results, the interaction and coordinated relation of the three kinds of deformation mechanism in deformation processes are discussed.
