Effect of roll speed and ejection pressure on the surface characteristics of Al-12mass%Si alloy foil rapidly solidified by single roll method
The geometric uniformity on the surface of foils rapidly solidified depends on the roll speed and ejection pressure. The wetting pattern irregularity was fabricated on the roll contact side of foil when the roll speed was low, and that irregularity was eliminated when the roll speed was high. The we...

| Abstract | The geometric uniformity on the surface of foils rapidly solidified depends on the roll speed and ejection pressure. The wetting pattern irregularity was fabricated on the roll contact side of foil when the roll speed was low, and that irregularity was eliminated when the roll speed was high. The wetting pattern on the roll contact side surface was consist of the uncontact area and directly contacting area. The uncontact part in the wetting pattern was reduced in size by increasing the roll speed and ejection pressure. The percentage of contact area where the foil contacted to the roll was 70-80% and the contact area increased when the roll speed and ejection pressure increased. The roughness of rotating direction of the roll contact side surface was smaller than that of the lateral direction. The roughness of roll contact side surface decreased with increasing of the roll speed and ejection pressure. |
