Abstract The dynamic phenomenology of melt spinning with four different nickel-metalloid alloys on copper, molybdenum, aluminium, and iron wheels as well as nickel- and chromium-plated copper substrates has been evaluated. Puddle dimensions are self-adjusting so that the integrated heat flux through the puddle/substrate contact area is sufficient to convert the melt into foil at the same mass flow rate. The dynamic wetting phenomena are complex because mechanical forces dominate during the initial liquid spreading stage, and the solidification process is highly influenced by the melt/substrate interface conditions. Melt spinning does not automatically produce thin section foils with uniform through thickness microstructure. While structural uniformity frequently occurs with “easy” glass-forming alloys, lower metalloid content alloys often develop graded through-thickness microstructures. When this occurs, the degree of crystallinity in the contact surface layer is frequently greater than in the opposite free surface layer.
