An exemplary image of the present alloy solidified as a 2 mm cylinder in CMC, i. e. imposing radial heat flux, is shown in Fig. 1 which summarizes all varied features of the microstructure. Similar features were also found in the 1 mm cylinder, in the part of the arc melted ingot in contact with the copper hearth, and in portions of ribbons. The first phase nucleating heterogeneously on the external surface was most often the CoSi compound whose crystals grew to the size of some microns rejecting Si into the liquid phase.
