The 12 pages that link to Annealing, each with the reason it gives.
SteelRelated: Annealing makes steel easier to form or machine and can restore ductility.
BronzeRelated: Bronze workers used annealing between hammering stages to reduce brittleness.
Grain growthRelated: Annealing often permits grain boundaries to migrate and grains to grow.
Copper metallurgyRelated: Annealing restores ductility to copper hardened by repeated hammering.
GlassblowingRelated: Newly formed glass must cool gradually to avoid cracking from thermal stress.
Float glassRelated: Float glass passes through an annealing lehr to reduce stresses before cutting.
