method and device for the production of metalllegierungsk amp; all; rpern with localized small korngr amp; all; amp; w en.

摘要

the invention concerns a method for the production of metal alloys, especially magnesium alloys with low korngr & all; & w; s within a non extruded metalllegierungsk & all; rpers, as well as a device for carrying and professional; implementation of the method and a product which, after d a erfindungsgem & auml; & w; s procedure is established.by a cyclic, ortsabh & auml; ngig alternating exposure of teilfl & auml; chen of the oberfl & auml; che non - extruded metalllegierungsk & all; rpers these locally compressed and uncompressed.this r & t.; hrt, in conjunction with a prozesstemperatur of up to 600 & deg; c of the metalllegierungsk & all; rpers, to reduce the korngr & all; & white; the alloy at the oberfl & auml; che, a significant improvement in the walzf & auml; for the metalllegierungsk & all. rpers to f olge.
