1. Partial melting occurs where the solidus and liquidus temperatures are different. 2. The wetting time ideally stays below 60 seconds above liquidus . 3. For this distinction, the solidus may be contrasted to the liquidus . 4. The liquidus temperature can be contrasted to the solidus temperature. 5. The liquidus is the temperature above which the substance is stable in a liquid state. 6. The time in this area is known as " Time Above Liquidus ". 7. It can be seen that there are two lines, representing the solidus and liquidus . 8. Additional time above liquidus may cause excessive intermetallic growth, which can lead to joint brittleness. 9. SSM is done at a temperature that puts the metal between its liquidus and solidus temperature. 10. Phosphorus depresses the liquidus temperature, allowing the iron to remain molten for longer and increases fluidity.
