Asymmetric rolling of metal powders. I. Compactability of metal powders in asymmetric rolling

The compactability of iron powders and electrolytic titanium using driven rolls of different diameters at the same angular velocity is examined. The roll diameter ratio is 1.12 to 1.42. It is established that the rolling force can be decreased from 20 to 50% in asymmetric rolling depending on variation in the mismatch of circumferential velocities or diameters of the rolls as compared with conventional (symmetric) rolling at the same density of rolled product.
