Integral‐breadth analysis of X‐ray line broadening in cold‐worked natural molybdenite (MoS2) crystals

Abstract

An anomalous X‐ray line broadening effect has been studied in cold‐worked natural molybdenite (MoS2)crystals using the integral‐breadth method. The stacking‐fault probability is calculated on the basis of simple h.c.p. structure and is found to be approximately 0.03 on taking account the glide on S–S (sulphur–sulphur) slip planes only. Also, lattice strain and domain‐size parameter have been estimated. The dislocation density calculated from the domain‐size is found to be ≈2.6 × 1010 cm/cm3. A justification for using the simple h.c.p. structure theory for molybdenite has also been given. Copyright © 1972 WILEY‐VCH Verlag GmbH & Co. KGaA
