The MW wind turbine casting was prepared by metal mold gravity casting process. In order to improve the mechanical properties of the MW wind turbine via modifying the casting technology, the impact toughness of the MW wind turbine was studied under different sampling directions, impacting ways, and shocking temperatures. The results showed that the impact toughness of the MW wind turbine has significant differences under different sampling directions and impacting conditions. Moreover, it is worth mentioning that the impact toughness taken along the direction of metallic fiber is distinctly higher than the ones of other directions.
