Sažetak
An indirect method for the determination of stacking fault energies (SFE) of pure metals by X-ray diffraction technique is reported. The existing methods for the calculation of SFE suffer from simplified assumptions regarding dislocation distribution and type of dislocation present in the specimen. The present method is based on the strain field model of dislocations assuming a restrictedly random dislocation distribution. The method is applied for the calculation of SFE of plastically deformed copper and the values come out to be very close to those obtained from direct observation methods like TEM.
