TEXTURE ANALYSIS OF ZIRCALOY-4 USING WILLIAM-IMHOF-MATTHIES-VINEL (WIMV) METHOD. Zircaloy-4 as a nuclear fuel cladding has been widely examined macroscopically and microscopically, but research using neutron diffraction technique, especially the characterization of crystallite orientation (texture) in Indonesia is still rare. The purpose of this study is to apply the methods of William-Imhof-Matties-Vinel (WIMV) on the characterization of zircaloy-4 material texture. WIMV is one of data analysis method for textures materials obtained by neutron or x-ray diffractions technique. The analysis is obtained that 002 pole figure has the largest texture index (F2 ) compared to the others pole figures, that are 100, 101, 102 and 110. Index texture (F2 ) of pole figure 002 for incomplete pole figures, F2 = 4.69 m.r.d with a reliability factor RP0 = 3.28%, and recalculated pole figures, F2 = 4.42 m.r.d with RP1 = 2.97%. For all pole figures, it is obtained that a reliability factor of the average RP0= 6.60%, RP1 = 5.02%, entropy = - 0.5871, and texture index (F2 ) = 2.34 m.r.d. Data analysis showed that the WIMV method can be used to determine the direction of the crystallite orientation of the pole figure where the most powerful texture leads to the <001>(c-axis direction) in a hexagonal structure.
