Abstract (en)
Method and device for manufacturing articles for magnetic use which are composed of a metal alloy taking the form of a continuous strip (3) from which the articles (33) are cut out, the alloy being subjected to a heat treatment comprising at least one annealing operation carried out in the presence of a magnetic field. <??>The annealing operation is divided into at least two successive phases, respectively a first initiation phase in the presence of a magnetic field, carried out on the move on the alloy in the form of a continuous strip (3), and a second ageing phase carried out on the separate articles (33) obtained from the strip (3) which has undergone the first initiation phase. <??>The invention makes it possible to produce articles in particular for the electrotechnical industry. <IMAGE>
