Widmanstatten Pattern - Web learn how the widmanstätten pattern forms in the metal cores of partially molten asteroids and how it reveals the size and cooling rate of the parent body. See factors such as composition, cooling rate, and diffusion that influence the pattern and its size. Web this form of widmastätten ferrite gives a low nucleation rate and slow growth to very large plates (visually resolvable) under local equilibrium conditions and so differs from that forming at the top of the lower ‘c’ curve ( fig. 6.3 ), when growth occurs under paraequilibrium (parae) conditions at rates between 50 and 550 μm s − 1 in low c weld. The kamacite is in the form of plates that have exsolved, parallel to the faces of. Núñez monrroy of the pontifical catholic university of peru. Web discover the fascinating story behind the widmanstätten pattern, a unique crystal structure found in muonionalusta meteorites. The pattern is named for alois von widmanstätten, a viennese scientist who discovered it in 1808. While working at the fabriksproduktenkabinett, he began to examine iron meteorites along with karl von schreibers. A table is provided to determine the angles within the widmanstätten pattern as a function of orientation of the slice, and methods are provided to solve the inverse problem, namely to determine the orientation of the slice from measurements of the widmanstätten pattern.
