Gradient structure produced by three roll planetary milling: …
In this study a gradient grain structure was produced by processing rod billets through three roll planetary milling (also known as PSW process). This kind of gradient structure is reported to provide an excellent combination of strength and ductility owing to an ultrafine-grained surface layer and a coarse-grained interior of the billet.

Experiments of Three-Roll Planetary Rolling
A PSW testing mill has been designed and manufactured by the present authors. A mathematical model using stream functions and the upper bound method has been proposed by one of the authors [11] to simulate the plastic deformation behavior of a rod at the roll-gap during PSW rolling.

Three-Roll Planetary Rolling Mill Motion Analysis and Test …
In rolling process, rolling vibration can be restrained by improving roll lubrication, reasonably distributing rolling force of each rolling mill, increasing billet temperature, reasonably arranging …
Analytical and experimental study on the spiral marks of …
Three-roll planetary mills are also called planetenshragwalzwerk (PSW) [11], [12] mills or high reduction machine () [8], because the area reduction achieved by one rolling pass of a PSW mill is approximately equivalent to that by 6–8 rolling passes of a traditional mill.
Three-Roll Planetary Rolling Mill Motion Analysis and Test …
In rolling process, rolling vibration can be restrained by improving roll lubrication, reasonably distributing rolling force of each rolling mill, increasing billet temperature, reasonably arranging roll diameter and reducing rolling inlet tension.
