摘要

The influence of process parameters on geometry and the quality of amorphous ribbons produced by the Chill Block Melt Spinning (CBMS) method from, Fe82B18, Fe79.7V2.3B18, Fe77.5V4.5B18 and (Co,Ni,Fe)(73)(B,Si)(27) (in at%) alloys was studied experimentally and theoretically. The assessment of the forces, acting in the melt-substrate contact zone, showed that at CBMS the puddle is shaped by a hydrodynamic mechanism. Thus, by implementing the ideas of the dimensional analysis and solving the equations of heat and momentum transfer, it was possible to obtain a general functional dependency between the process parameters and the geometry of the final product at CBMS (amorphous, or microcrystalline, ribbon). A method for the evaluation from the experimental data of the inherent to the dimensional analysis unknown parameters was developed and tested. The functional dependency was used: (1) to predict the ribbon geometry as a function of the process parameters; (2) to evaluate the cooling rates achieved during the processing of the amorphous ribbons.
