Solder Tin Lead Eutectic Alloy nuclear-power

Solder Tin Lead Eutectic Alloy. Soldering is a technique for joining metals using a filler metal alloy that has a melting temperature less than about 425°C (800°F). Because of this lower temperature and different alloys used as fillers, the metallurgical reaction between filler and work piece is minimal, resulting in a weaker joint.

Eutectic research. No. 1.—The alloys of lead and tin

Attempts to prepare pure eutectic alloys of known constitution led to the discovery of discrepancies between the authors’ experiments and the data on lead-tin alloys published by Roberts-Austen. A complete redetermination of the equilibria of the lead-tin system was therefore undertaken, by both pyrometric and microscopical methods.
