The most commonly used measures to improve metal plasticity

Increasing temperature, stress heat treatment and adding alloying elements.

1, metal has good plasticity at high temperature, and heat can make its crystal structure irregular, so it is easy to deform.

2. Stress heat treatment: This is a process of heating and cooling materials to increase their plasticity. This process involves heating the material above the critical temperature, and then rapidly cooling it to generate stress, thus making it more easily deformed.

3. Adding some metal elements, such as aluminum, magnesium and titanium, can improve the plasticity of metal and reduce its brittleness.
