摘要： A process and apparatus for producing articles for magnetic use consisting of a metal alloy in 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, initiating phase in the presence of a magnetic field, carried out on the alloy in the form of a continuous strip (3) as it unwinds, and a second phase of ageing carried out on the separated articles (33) obtained from the strip (3) which has undergone the first phase. The invention enables the production of articles, in particular, for the electrotechnical industry.
