Annealing

What is Annealing process: A Guide to Strengthening Materials

未分类 / /

What is Annealing? Annealing process, derived from the word “Anneal,” meaning to heat, originates from the concept of fire. It refers to a softening or heat treatment process applied to materials, especially metals and glass, to alter their physical properties and characteristics. The annealing process makes materials softer, more ductile, and less prone to breakage
