Ribbons of pure tin (99.9999%) and dilute Sn-Ge alloys, prepared by melt spinning using a 4′ diameter copper cylinder, were strained in tension. Reversible strains of a few percent were recorded in the dilute alloys but not in the pure tin. X-ray diffraction examination suggests that this pseudoelasticity is due to twinning rather than a martensitic transformation.
