Pattern Formation by Spinodal Decomposition in Ternary Lead-Free Sn-Ag-Cu Solder Alloy

Metals, 2022
In comparison to Pb-based solders which have a toxic effect, the tin-silver-copper (SAC) family of alloys have relatively strong reliability and are widely used in the electronics industry.

Not invasive analyses on a tin-bronze dagger from Jericho. A case study [PDF]

, 2018
Tin-bronze makes its appearance in Southern Levant during the Early Bronze IV, the post-urban phase of the last centuries of the 3rdmillennium BC, when arsenical copper was still the most widespread copper alloy. Only from the following Middle Bronze Age

In situ transformation and cleaning of tin-drop contamination on mirrors for extreme ultraviolet light

, 2018
Tin-drop contamination was cleaned from multilayer-coated mirrors by induction of phase transformation. The {\beta} - {\alpha} phase transition of tin was induced to initiate material embrittlement and enable facile removal of thick tin deposits.
