I have been working as an engineer and metallurgist for 15 years. I am currently working on a project at Georgia Tech to complete my thesis and obtain a master's in Materials Science and Engineering. My project involves analysis of several thousand optical images of the microstructures of alloys of tungsten, iron, copper, and nickel processed by liquid-phase sintering. The samples were processed aboard the Space Shuttle, so they represent how these microstructures evolve with sintering time absent the effects of gravity. I am using Mathematica to analyze the images, specifically to make measurements of the angles formed at the triple points where tungsten particles make contact with each other and form a "neck" between them and thus the solid-solid boundary intersects the two liquid-solid boundaries at the respective particle surfaces. These angles are commonly referred to as "dihedral angles" in the literature.
