Garnet Phase
Garnet phase is a special intermetallic phase in non-ferrous materials that suppresses dislocation movement and improves mechanical properties.
Physical-Chemical Mechanism of Action
The garnet phase forms through a special crystal structure of various metals. It prevents atoms from diffusing and changing positions (dislocation movement).
Metallurgical Relevance & Risks in Welding
The presence of the garnet phase increases strength and toughness, prevents cracks, and improves the strength-to-weight ratio. Incorrect welding or too high temperatures can decompose the garnet phase, impairing mechanical properties.
Workshop Practice & Instructions
To preserve the garnet phase during welding, it is important to control the maximum melting temperature and cooling rate. For special non-ferrous materials, welding parameters (temperature, time, voltage) must be strictly adhered to maintain the garnet phase and utilize its beneficial properties.
