= Whisker (metallurgy)
{wiki=Whisker_(metallurgy)}
In metallurgy, a whisker refers to a very thin, hair-like crystal structure that can form in certain materials, particularly metals and semiconductors. These whiskers are typically single crystals that can grow spontaneously from the material and can have significant implications for the mechanical properties and performance of the material. Whiskers can be formed during the processing or fabrication of materials, often as a result of specific conditions such as thermal stress, impurities, or phase changes.
