 Annealing- a heat treatment that typically involves heating a metallic material to a high temperature for an extended period of time in order to lower the dislocation density and hence impart ductility  ASTM- American Society for Testing and Materials  ASTM grain size number [n]- a measure of the size of the grains in a crystalline material obtained by counting the number of grains per square inch at a magnification of 100  Burgers vector- the direction and distance that a dislocation moves in each step, also known as the slip vector  Critical resolved shear stress- the shear stress required to cause a dislocation to move and cause slip  Cross-slip- a change in the slip system of a dislocation  Defect chemical reactions- reactions written using the Kroge
