Widmanstatten Patterns - 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. This pattern is known as the “widmanstätten figure” (see metallurgy, fig. Web widmanstätten pattern, lines that appear in some iron meteorites when a cross section of the meteorite is etched with weak acid. Web the cores of iron meteorites exhibit beautiful widmanstätten patterns, as shown below in the alvord meteorite (photo by jim h): It has been estimated that it took about 1000 years for these molten remnants of planetary core to cool by just 1 degree celsius! Web 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. The widmanstätten pattern is thought to form by the nucleation and growth of kamacite from taenite during slow cooling of the parent meteorite body (owen and burns 1939). This paper summarizes our recent evaluation of the various mechanisms for the formation of the widmanstatten pattern.
