# The components of a unit vector are equal to e cosines – METALLURGY – 583

The components of a unit vector are equal to e cosines of the angle between the vector the cosines of the angle between the vector and each (orthogonal, Cartesian) reference xis. a s e can use xis transformations describe We can use axis transformations to describe vectors in different reference frames (room, specimen, crystal, slip system….) 3/25/2011 118 Standard Stereographic Projections Standard Stereographic Projections Standard Stereographic Projections Standard Stereographic Projections Pole figures are useful because standardized xtures produce familiar recognizable textures produce familiar, recognizable diagrams. tandard Stereographic (SS) projections Standard Stereographic (SS) projections provide maps of low index directions and planes. PFs from single crystals can be constructed from SS projections by deleting all except one Miller index. 3/25/2011 119 ole Figures ole Figures ole Figures ole Figures Pole Figures Pole Figures Pole Figures Pole Figures tereographic Stereographic projections with a specified orientation relative to the specimen that shows the variation of pole density with pole rientation for a given orientation for a given set of crystal planes. 3/25/2011 120 Stereographic projection of 3 &lt,100&gt, poles Pole Figures Pole Figures – cont’d cont’d Pole Figures Pole Figures – cont’d cont’d Several Projected Poles Crystals Near a single rientation orientation Intensity Distribution 3/25/2011 121 ole Figure Plot ole Figure Plot ole Figure Plot ole Figure Plot Pole Figure Plot Pole Figure Plot Pole Figure Plot Pole Figure Plot ODF project: C:…Harry dataH1_111.rw 1 Pole figure: 111 Raw 2Theta: 38.4200 Dim ension: 2D h idt ODF project: C:…Harry dataH1_200.rw 1 Pole figure: 200 Raw 2Theta: 44.6200 Dim ension: 2D h idt ODF project: C:…Harry dataH1_220.rw 1 Pole figure: 220 Raw 2Theta: 65.0100 Dim ension: 2D h idt Projection: Schmidt Scale: Linear Color m ap: X’Pert Grid settings: Psi Phi First Last 90 360 Step 30 90 Projection: Schmidt Scale: Linear… Type your question here!
