Abrégé
(DE)
Die Erfindung betrifft eine Verfahren zur Wärmebehandlung eines Kaltbandes mit einer Oberflächenbeschichtung aus Ni und/oder Co und eingebauten nichtmetallischen Elementen C und/oder S, gegebenenfalls unter Zusatz von Fe, In, Pd, Au und/oder Bi, wobei das Kaltband einen niedrigen Kohlenstoffgehalt aufweist. Da die an den Korngrenzen angelagerten Verbindungen aus C, S, N und P mit dem Oberflächenbeschichtungsmetall die meisten Mikrorisse bewirken, wenn keine Rekristallisation stattfindet, ist die Temperatur der Wärmebehandlung niedriger als die Rekristallisationstemperatur und höher als die Ausscheidungstemperatur zu wählen. Bei einer Rekristallisation würden die Korngrößen leicht die Dicke der Beschichtung erreichen, so daß die versprödenden Verbindungen mit den Korngrenzen aus der Beschichtung wandern würden. Durch die erfindungsgemäße Wahl der Temperatur der Wärmebehandlung der Oberflächenbeschichtung wird hingegen eine optimale Versprödung der Korngrenzen gewährleistet, was insbesondere bei der Herstellung von Batteriebechern von Vorteil ist. Weiterhin wird dass erfindungsgemäß hergestellte Blech und der entsrpechende Batteriebecher beschrieben.
(EN)
The invention relates to a method for heat-treating a cold-rolled strip with an Ni and/or Co surface coating and incorporated non-metal elements C and/or S, and optionally adding Fe, In, Pd, Au and/or Bi, said cold-rolled strip having a low carbon content. Since the compounds formed by C, S, N and P with the surface coating metal and attached on the grain boundaries are the most frequent cause of cracks if no recrystallization takes place, the temperature of the heat treatment should be lower than the recrystallization temperature and higher than the precipitation temperature. In the case of recrystallization, the grain sizes would easily reach the thickness of the coating so that the embrittling compounds would migrate from the coating together with the grain boundaries. By selecting the temperature of the heat treatment of the surface coating according to the inventive method, an optimum embrittlement of the grain boundaries is obtained, which is especially advantageous in the production of battery cans. The invention further relates to a sheet metal producible by said method and to a corresponding battery can.
(FR)
L'invention concerne un procédé de traitement thermique d'un feuillard laminé à froid avec un revêtement de surface Ni et/ou CO et des éléments non métalliques C et/ou S intégrés, avec addition éventuelle de Fe, In, Pd, Au et/ou Bi, ledit feuillard présentant une faible teneur en carbone. Comme les composés de C, S, N et P présents sur les joints de grains provoquent le plus de microfissures avec le métal de revêtement de surface en l'absence de recristallisation, la température de traitement thermique est inférieure à la température de recristallisation et supérieure à la température de précipitation. Dans le cas d'une recristallisation, les granulométries atteindraient aisément l'épaisseur du revêtement, et les composés fragilisés migreraient avec les joints de grains à partir du revêtement. Le choix de la température de traitement thermique selon l'invention permet en revanche d'assurer une fragilisation optimale des joints de grains se révélant particulièrement avantageuse dans la fabrication de boîtiers de batteries. L'invention concerne également la tôle et le boîtier de batterie obtenus selon l'invention.
