| Abstract: | This paper highlights a quantitative analysis of microstructure of model forging of 2618 aluminum alloy, depending on thermal simulation experiment on the Gleeble-1500 machine and XJG-05 metallographic analysis and combined with isothermal forming production techniques of Z-9 plane back rocker model forging. This paper discusses the influence of deformation temperature, deformation rate and deformation degree on grain size, provides the reasonable techniques parameters and presents solution to the coarse-grained problem arising from the practical production. |
