Annealing is a metal heat â?? treatment process. It involves slowly heating the metal to a certain temperature, maintaining this temperature for a sufficient period, and then cooling it at an appropriate rate. Sometimes, the cooling is natural, while other times, the cooling rate is controlled. This process is crucial for modifying the properties of metals.
