Abstract
Hard difficult-to-roll alloys are shaped by forming a mold of plastic, especially a polyacrylate, with a highly smooth surface onto which the alloy is deposited by low-temperature arc vapor deposition. The alloy layer is then separated from the plastic substrate and subjected to heat treatment to increase its density.
