Thermomechanical Processing
Thermomechanical treatment combines forming and heat treatment to optimize the microstructure and improve mechanical properties. This prevents cracks and increases strength.
Physicochemical Mechanism of Action
Thermomechanical treatment (TMT) involves a combination of forming (e.g., pressing, drawing) and heat treatment (melting, cooling). This leads to a change in the crystal lattice of the material, improving mechanical properties.
Metallurgical Relevance & Risks in Welding
TMT prevents cracks and increases the strength and toughness of the weld. Improper application can lead to overstressing the material, resulting in fractures or deformations.
Workshop Practice & Instructions
When performing TMT, it is important to ensure correct forming and the right temperature profile. Forming should be done slowly to avoid overstressing the material. The temperature profile should be maintained so that the material stays in the critical temperature zone to achieve optimal microstructure.
