A simple, accurate and flexible method is describedfor the preparation of composite samples from metal sheets. Thebasic technique can be adapted to conserve material or for themeasurement of thick plate specimens. Any combination of the fourpossible quadrants of the polefigure can be determined singly orcombined. In its routine application the technique is ideallysuited to the measurement of three complete polefigures for thedetermination of orientation distribution functions. In particular,the through thickness integration, sheet area sampling and applicabilityto large grained materials make it suitable for the measurementof texture for comparison with bulk physical properties.Complete instructions are given for the application of the techniquein practice.
