Crystallographic relationship
WebA crystal structure is a unique arrangement of atoms, molecules or ions in a crystal. It is composed of a motif, which is a set of atoms arranged in a particular way, and a lattice. Motifs are located upon the points of lattice, which is an array of points repeating periodically in three dimensions. WebThe crystallographic axes are imaginary lines that we can draw within the crystal lattice. These will define a coordinate system within the crystal. For 3-dimensional space lattices …

WebOct 15, 2009 · The crystallographic orientation relationships that are active during the transformation of austenite to bainite are studied for two TRIP steels by means of Electron BackScatter Diffraction (EBSD). A detailed evaluation of about 360 retained austenite grains and their BCC neighbours was performed. Three relationships were considered, … WebThis leads to a five-parameter description of a crystallographic relationship [ 4, 14, 15 ]. Here, the focus is on the three misorientation parameters [ 16, 17 ]. Misorientations, between crystals of the same or different phases, often occur repeatedly near to …
WebNov 25, 2024 · To analyze the crystallographic relationship, prior γ orientation was determined through a calculation using the orientations of the martensite blocks. In this calculation, an orientation relationship that deviates from the K–S relationship by a few degrees is assumed between the martensite and γ .
