11. The solidus is always less than or equal to the liquidus , but they need not coincide. 12. A non-eutectic formulation must remain still as the temperature drops through the liquidus and solidus temperatures. 13. The inclusions preserved original melt and therefore can provide the magmatic condition where the melt is near liquidus . 14. The freezing range corresponds directly to the liquidus and solidus found on the phase diagram for the specific alloy. 15. Soft solder filler metals are typically alloys ( often containing lead ) that have liquidus temperatures below 350 �C. 16. Temperature ranges for solidus and liquidus ( the boundaries of the mushy state ) are listed as solidus / liquidus. 17. Temperature ranges for solidus and liquidus ( the boundaries of the mushy state ) are listed as solidus / liquidus . 18. Time above liquidus ( TAL ), or time above reflow, measures how long the solder is a liquid. 19. Coring is predominantly observed in alloys having a marked difference between liquidus and annealing and / or hot-working. 20. The liquidus temperatures of these flows were in excess of } } with viscosities as low as 100, 000 poise.
