  What Is Annealing?- Definition, Process, And stages

  What Is Annealing? Annealing is a heat treatment process used mostly to increase ductility and reduce the hardness of a material. This change in hardness and ductility is a result of the reduction of dislocations in the crystal structure of the material being annealed. Annealing is often done after the material has undergone a hardening or cold ...

  Modern and New Technologies in Copper Production

  2020826 · In later times, as humans learned to mine and process ore, ore processing technologies emerged. Previously, metal products were made by cold processing of metals. Copper and iron are limited in their use because of the difficulty of cold processing. After the invention of the heat treatment of metals, copper products began to spread.
