[origin: US6159307A] PCT No. PCT/EP97/06394 Sec. 371 Date Jun. 11, 1999 Sec. 102(e) Date Jun. 11, 1999 PCT Filed Nov. 17, 1997 PCT Pub. No. WO98/27243 PCT Pub. Date Jun. 25, 1998Process to avoid adhesions during the annealing of non-ferrous metal alloys, comprising the heating, holding and cooling phases, whereby the material being annealed is exposed to an inert or oxidizing protective-gas atmosphere during the structure transformation, as a result of which a thin oxide layer is formed during this time on the surface of the material being annealed and/or an oxide layer that was previously there is maintained, thus preventing the non-ferrous metal objects from adhering together.
