Abstract
During the storage of a Sn-6.6Lu alloy in air for several days, large amounts of thread-like tin whiskers appear on the oxidized surface of Lu4Sn5 precipitates in this alloy. Storage at 150 °C for 30 min causes hillock-type whiskers to form. The driving force for whisker growth in this Sn-6.6Lu alloy is the compressive stress resulting from the diffusion of oxygen into the lattice of the Lu4Sn5 precipitates. © 2006 Acta Materialia Inc.
