Neulasmaisiset
Neulasmaisiset are a class of microstructural patterns observed in certain solid materials, characterized by elongated, needle-like precipitates embedded in a host matrix that together form a mosaic-like arrangement. The term is of Finnish origin, combining neula meaning needle with maisiset, a suffix used in technical compound nouns to denote a set or assembly.
Historically, the concept was described in metallurgical and ceramic research in the late 20th century as researchers
In typical neulasmaisiset, the needles align along preferred orientations, creating domains with distinct optical or mechanical
Applications include materials design where directional strength, toughness, or thermal conductivity are desired. By adjusting composition,
Characterization is performed using transmission or scanning electron microscopy, electron backscatter diffraction, and X-ray diffraction, which
