Summary:
Single roll melt spinning is a non-conventional forming process used to produce rapidly solidified thin ribbons as a near-net shaper by direct casting from the liquid state. In this paper, a single roll made from brass with a diameter of 150 mm was used to produce rapidly solidified Al-Mg alloy ribbons. The ribbons are produced with thicknesses in the range of 20 to 330 μm. The results exhibited unique advantages in refining the microstructure and modifying the mechanical properties of these ribbons. The hardness was improved to about twice the original hardness of the alloy. Moreover, corrosion resistance of alloy was improved and their rate was reduced from 10.02 to 1.643 mpy for alloy type 5052 and from 6.91 to 1.943 mpy for 5083.
