Defects in Metal Material Forming Processing, Part 13

Defects in metal forming processes can arise due to various factors, including material properties, process parameters, and environmental conditions. Here are some common defects associated with metal forming:

Uneven Composition and Structure

After rolling or annealing, the chemical composition of different parts of the product is greatly different, which is called uneven composition. Uneven composition can cause differences in color or deformation characteristics.

Macroscopic inspection can show component segregation points or segregation areas, differences in microstructure and performance, and even cracking.
