Measurements of geometrical parameters of clad wires

The measurements of geometrical parameters of the FeNi42Mn1/Cu clad wires obtained by various deformation schemes have been presented. Analysis of geometrical parameters of a wire cross-section was made by means of a computer program for digital image analysis. The measurements of geometrical parameters of several sets of clad wires 0.30 mm in diameter obtained by different drawing schemes show that thickness non-uniformity of an outer layer was small, within a range specified by the ASTM F29 standard.
