According to an embodiment, a method to evaluate forgeability of an aluminum alloy first of all prepares an aluminum alloy material as a target specimen. The aluminum alloy material is compressed and transformed with a predetermined deformation rate at a testing temperature of 350-550°C. In the aluminum alloy material which is compressed and transformed, at least one of appearance observation, micro-structure observation, and flow stress behavior observation is implemented. |
