Crystallographic meaning
WebA crystal may be regarded as built up of primitive parallelepipeda, the edges of which are in the ratio of the crystallographic axes, and the angles the axial angles of the crystals. To … WebDefinition. The term R factor in crystallography is commonly taken to refer to the 'conventional' R factor. a measure of agreement between the amplitudes of the structure factors calculated from a crystallographic model and those from the original X-ray diffraction data. The R factor is calculated during each cycle of least-squares structure ...

WebCrystallographic texture has an impact on the activities and roles of all the slip systems. In many cases, it is sufficient to consider the initial orientation of the c-axes, particularly if one simply wants to determine the relative importance of deformation mechanisms since c-axis orientation strongly influences the ease of basal slip and ... WebExample 31.2. 1. Solution. Contributors and Attributions. The orientation of a surface or a crystal plane may be defined by considering how the plane (or indeed any parallel plane) intersects the main crystallographic axes of the solid. The application of a set of rules leads to the assignment of the Miller Indices ( hkl ), which are a set of ...
WebIn crystallography, the R-factor (sometimes called residual factor or reliability factor or the R-value or R Work) is a measure of the agreement between the crystallographic model and the experimental X-ray diffraction data. In other words, it is a measure of how well the refined structure predicts the observed data. [1]
