Purpose – The purpose of this paper is to present an analysis over own and other authors data related to the process of Chill Block Melt Spinning (CBMS) and propose a model of analysis for interpreting. Design/methodology/approach – The methodology used in this work is to present the data analyzed by other authors, organize own data similarly to establish comparison, and established models and propose a possible physical processes interpretation. Findings – Similarity between own experimental data. with others data reported by other authors, both z/w ratio and the thicknesses of the films produced has been found. This allows us to establish an exponential decay of the parameters studied and possibly link it the Newtonian cooling to which the samples are subjected in its production. Research limitations/implications – This work is the first model set up to predict dimensions in design process by CBMS as a function of parameters of the ribbon production process. Practical implications – The prediction of the product dimensions, with adjusting the initial parameters, allows to improve the process of ribbon production, this saves tuning time of the machine and provides certainty in the molten material ejection. Social implications – The efficient production of magnetic materials lets save efforts in the raw material process preparing in magnetic cores for the energy sector. This, improves production besides benefit society by the final product and the energy savings. Originality/value – The value of this paper is to propose a model of analysis that allows standardize production parameters, and could even allow the use of these models in computer programs, process simulators in a more effective manner.

We report on synthesis and characterization of a novel group of compounds based on copper, gadolinium, and calcium. Cu-Ca and Cu-Gd binaries were previously studied while Ca and Gd are known to be immiscible themselves. The effects of substituting Gd with Ca in Cu5Gd1-xCax compounds (0≤x≤1) were studied by investigating the phase stability and crystal structure of the resulting new compounds in five specimens with x = 0, 0.33, 0.50, 0.66, and 1, respectively. The samples produced by melt-spinning had hexagonal P6/mmm structure, irrespective of Ca amount (x), where lattice parameters varied with x linearly. This is an indication of good solid solubility under the preparation conditions. A slower cooling upon arc-melting caused the liquid phase separation into Cu4.5Gd and Cu-Ca compounds. Using TEM, rapidly solidified ribbons (Cu5Gd0.5Ca0.5) were investigated and the formation of a homogeneous ternary phase with a nearly nominal stoichiometric composition and minor amounts of Cu-Ca secondary phase was observed. Using DSC and HT XRD, we found that these systems are stable at least up to 400°C. Upon a 16-hour hydrogenation at 1 bar and 300°C, all specimens absorbed about 0.5 wt.% of hydrogen. This caused changes in structure with the formation of pure Cu and H2Gd1-xCax solid solution.
