Abstract : The Finemet (Fe73.5Si13.5B9Cu1Nb3) alloy has exhibit the best combination of soft magnetic properties (high permeability, high saturation magnetization and low coercivity) as compared to the other traditionally available materials. These alloys are prepared using planar flow melt spinning process. The soft magnetic properties of the alloy depend on the composition and process parameters such as wheel speed, nozzle-wheel gap, ejection pressure and melting temperature. It has been observed that good quality amorphous ribbons can be obtained by selecting optimum process parameters. The investigation deals with the optimization of process parameters to obtaining quality amorphous ribbons during planar flow melt spinning experiments. The alloy was melt spun to obtain rapidly solidified ribbons using an L16 orthogonal array as specified by Taguchi technique; varying process parameter such as wheel speed (V), nozzle-wheel gap (G), melting temperature (T) and ejection pressure (P). It has been observed both the thickness and width decrease along the length of the ribbon. The results are analyzed using Taguchi ANOVA method. The percentage contribution of each control parameters has been calculated, which influences the thickness and the surface roughness of the ribbon has been obtained statistically using analysis of variation (ANOVA) method. Keywords:- Process Parameters, Taguchi orthogonal array, ANOVA method.
