With increasing work hardening during deformation, both the hardness and strength of the worked part increase significantly, and intermediate stress relief annealings are necessary to minimize the hazards of cracking (laminating) and to avoid overstraining the working tool.
Sa pagtaas ng work hardening sa panahon ng pagpapapangit, parehong ang tigas at lakas ng nagtrabaho pagtaas bahagi nang malaki-laki, at intermediate ang stress na lunas annealings ang kinakailangan upang i-minimize ang panganib ng crack (laminating) at upang maiwasan ang overstraining ang working tool.
