It changes the physical and sometimes chemical properties of the material to improve ductility and reduce hardness, making it easier to machine.
By: SANS Machining Annealing process is one of the commonly used heat treatment processes, mainly used to increase the ductility of materials and reduce their hardness. This change in hardness and ductility is the result of a decrease in dislocations in the crystal structure of annealed materials. Annealing is usually carried out after the material has undergone a hardening or cold working process to prevent brittle failure or make it more ductile in subsequent operations. Why Is Metal Annealed? As mentioned above, annealing is used to reduce hardness and increase ductility. It is important to change these mechanical properties through annealing for many reasons: Annealing improves the formability of the material. Hard and brittle materials are difficult to bend or press without damaging the material. Annealing eliminates this risk. Annealing can also improve machinability. Extremely brittle materials can cause excessive tool wear. Reducing the hardness of the material through annealing can reduce the wear of the tools used. Annealing to remove residual stress. Residual stress can lead to cracks and other mechanical complications, and it is usually best to eliminate them as much as possible. What Metals Can Be Annealed?
