Quantitative texture analysis reliability factors are examined from an experimental point of view, using real‐sample and modelled orientation distribution refinements. The classical RP factors of texture analysis are shown to depend on the texture strength, and their representation of the various textures is not homogeneous. The surface‐weighted RPw homologues exhibit lower texture strength dependency and better homogeneities, but still do not allow for comparison of refinements operated on samples with different textures. New factors, Rw, weighted by the counting statistics, show the lowest dependency and best homogeneity. From Rw1(Rw0) curves a new criterion is established, which allows the detection of poorly refined orientation distributions. This study highlights a unique entropy‐to‐texture index relationship, which also gives a new criterion for testing refinement reliability, and proposes two different ranges in which to apply the texture index and the entropy factors.

“…It is an important factor in the control of the properties of titanium such as ductility and fracture strength (Kocks & Westlake, 1967;Partridge, 1967;Mahajan & Williams, 1973;Yoo, 1981). Many studies have been carried out on mechanical twinning and texture in titanium and other metals (Bevis & Tomsett, 1970;Cheneau-Spä th et al, 1994;Balogh et al, 2009), as well as on the well established Dauphiné twin in quartz crystals (Chateigner et al, 2002). Twins can be described by elegant methods in mathematical crystallography (e.g.…”

Multiple twinning in pure hexagonal close-packed titanium

Commercial pure titanium (T40) was deformed in channel die compression by means of the split-sample technique in order to study multiple twinning. Particular attention was paid to the twin variant presentation and selection during multiple twinning. All possible misorientations, corresponding to the multiple twins arising from the combination of the {1122} compression (C) twin, the {1012} tension twin (T1) and the {1121} tension twin (T2), were calculated with respect to the crystal basis of the matrix grain. All the multiple twin variants are partitioned into ten classes with the same crystallographically equivalent misorientation angle and axis. However, when the influence of twinning order is taken into account, the multiple twin variants are partitioned into 15 classes. Experimental results prove that the selection of twin variants (primary and secondary) is mainly governed by their macroscopic Schmid factor (SF). The normalized SF is more efficient at predicting variant selection. A twin formed in one grain can activate another twin in a neighbouring grain, provided that the angle between the two twinning planes does not exceed 20 .
