Microstructural parameters such as coherent domain size, microstrain, dislocation density and texture of electrolytically plated Ni-Mn-S layers were investigated by X-ray analysis. Structural parameters, layer composition and the macroproperties are discussed and explained. With the help of a statistical regression analysis the correlation coefficient r(2) and its relationship with the investigated parameters is determined. It is shown that the microstructural parameters play an important role in determining the macroscopic properties. The manganese concentration is shown to influence the structural parameters, but no influence of sulphur is found. It seems that a relationship of the structural parameters with the macroscopic properties is valid in general and is not a special case. There structural correlations can be used in general for processing electrolytic deposits for required applications.
