What are the advantages and disadvantage of hard working of a metal?

The advantages of hard working a metal include increased strength, improved wear resistance, and enhanced mechanical properties, making it suitable for demanding applications. However, the disadvantages can include reduced ductility, which may lead to brittleness and an increased risk of fracture, as well as the possibility of residual stresses that can affect the material's performance. Additionally, hard working processes can be energy-intensive and may require specialized equipment.
