Epitaxy Induced orientation of the lattice of a crystal of a surface deposit by the lattice of the substrate crystal. A graphical representation of the temperature, pressure and composition limits of phase fields in an alloy system as they exist under conditions of thermodynamical equilibrium. In condensed systems, pressure is usually considered constant. Equiaxed Structure A structure in which the grains have approximately the same dimensions in all directions. Erichsen Test Similar to the Olsen Test.
Readings are in millimeters.
The height of the cup in millimeters at fracture is a measure of the ductility. Etchant A chemical solution used to etch a metal to reveal structural details. Etching Subjecting the surface of a metal to preferential chemical or electrolytic attack to reveal structural details. Etching In metallography, the process of revealing structural details by the preferential attack of reagents on a metal surface. An alloy having the composition indicated by the eutectoid point on an equilibrium diagram.
