Improper operation of aluminum alloy forging will appear lar

The large grains may be due to high forging temperature, insufficient deformation degree, high final forging temperature, or deformation degree falling into critical deformation zone. The deformation degree of aluminum alloy is too large to form texture, and the deformation temperature of superalloy is too low to form mixed deformation structure, which may also lead to the coarse grain.
The coarse grain size can reduce the plasticity and toughness of the forging and significantly reduce the fatigue performance of the forging. Uneven grain size can significantly reduce the durability and fatigue performance of the forgings.
