Tin plague

Tin plague, also known as zinc plague, is a phenomenon that can affect certain metallic surfaces, especially those that contain tin as an alloying element. This phenomenon results from a change in the crystal structure of the alloy, which can occur under certain conditions and can lead to considerable damage.

In the case of metallic surfaces affected by tin plague, the transformation of the crystal structure occurs due to low temperatures, usually below around 13 degrees Celsius. In this temperature range, the tin in the alloy can gradually change from a stable metallic phase to a less stable modification. This transition is accompanied by an increase in volume, which leads to internal stresses in the material.

The effects of tin plague on surfaces can manifest themselves in the form of cracks, fractures and even complete disintegration of the affected material. This phenomenon often only becomes visible after prolonged storage or exposure to specific conditions.

To minimise the effects of tin plague on surfaces, it is important to use alloys with a low tin content or to choose alternative alloying elements. Control of environmental conditions, particularly storage temperatures, plays a crucial role in minimising the risk of tin plague.

Historically, tin plague was a known problem, particularly with certain historical artefacts. However, in modern materials science, strategies are being applied to better understand and prevent the development of tin plague to ensure the integrity of metallic surfaces.
